Why Does Broccoli Have So Many Bugs? - Proper Way to Wash

-

 

Soak a head of broccoli in salt water and watch tiny creatures float to the surface. It's unsettling — but it's also normal. Broccoli's architecture makes it prime real estate for insects, and a quick rinse under the tap won't evict them. Here's why, how to wash properly, and which other vegetables need the same treatment.

Why Broccoli Attracts So Many Insects

The Floret Hiding Places

A broccoli head is thousands of tiny buds packed into a fractal canopy — countless crevices where small insects can hide from water, predators, and your eyes. A simple rinse flows over the surface; the residents stay dry underneath.

Cabbage Family Pests

Broccoli belongs to the Brassica family, which has dedicated pests: cabbage worms (the green caterpillars of the cabbage white butterfly), aphids, and thrips all target these plants specifically. Organic broccoli often hosts more of them, since fewer pesticides were used — a sign of cleaner farming, not dirtier produce.

What Kind of Bugs Are They?

The usual suspects are aphids (tiny soft-bodied clusters), cabbage worm caterpillars, and the occasional thrip or mite. They're harmless to humans — accidentally eating one won't hurt you — but they're unappetizing, and thorough washing removes them easily.

The Proper Way to Wash Broccoli

Step 1: Cut Into Florets First

Break the head into bite-sized florets before washing. This opens up the interior structure and exposes the hiding places that a whole head keeps sealed.

Step 2: Salt Water Soak

Dissolve 1–2 tablespoons of salt per quart of cold water and submerge the florets for 15–30 minutes. The salt irritates insects' bodies and drives them out — you'll see them floating on the surface. This is the single most effective step.

Step 3: Agitate and Rinse

Swish the florets vigorously in the soak, then lift them out and rinse thoroughly under cold running water to remove salt, debris, and any remaining insects. Drain in a colander and pat dry if roasting — wet broccoli steams instead of browning.

Alternative: Vinegar Soak

A solution of one part vinegar to three parts water, soaked 15 minutes, works similarly. Vinegar also helps dislodge dirt and some surface residues. Rinse well afterward.

What About Other Vegetables?

Cauliflower and Brussels Sprouts: Same Family, Same Problem

Cauliflower's curds hide insects exactly like broccoli florets — use the same salt-water soak. Brussels sprouts trap aphids between their tight outer leaves; peel the outermost leaves and soak the sprouts.

Leafy Greens: Lettuce, Spinach, and Kale

Aphids, slugs, and grit love leafy greens. Separate every leaf, soak in cold water, swish vigorously, and lift the leaves out (leaving grit at the bottom). A salad spinner finishes the job. Pre-washed bagged greens still benefit from a rinse.

Cabbage

Cabbage worms burrow between the tightly packed leaves. Remove the outer leaves, quarter the head, and soak in salt water before shredding.

Root Vegetables: Less of an Issue

Carrots, potatoes, and beets grow underground and mainly carry soil, not insects. A firm scrub under running water is sufficient — no soaking needed.

What NOT to Do

No Soap or Detergent

The FDA explicitly advises against washing produce with soap — residues can linger in crevices and cause stomach upset. Salt, vinegar, and water are all you need.

Don't Soak Too Long

Beyond 30 minutes, broccoli starts absorbing excess water, diluting flavor and turning mushy when cooked. Set a timer.

Frequently Asked Questions (FAQ)

Why does broccoli have so many bugs?

Broccoli's dense floret structure provides countless hiding places, and as a Brassica it attracts specialized pests like cabbage worms and aphids. A surface rinse can't reach them — only cutting into florets plus a salt-water soak drives them out.

Is it safe to eat broccoli if I find bugs?

Yes. The common insects on broccoli (aphids, cabbage worms) are harmless to humans. They're unappetizing but not dangerous — a proper salt-water soak and rinse removes them completely.

Norah Jones and Her Love of Wine with Dinner

-

Every artist in this series has a cocktail. Norah Jones has something better documented: a palate. The singer whose Come Away With Me became the defining dinner-party album of its century never developed a signature mixed drink — instead, across interviews with Wine Spectator and Wine Enthusiast, she has described a genuine, dinner-first love of wine that eventually made her the co-owner of a French winery. This is that story, told from the record. A Palate Built at the Dinner Table "I Developed a Taste for Good Wine" "I'm certainly no wine expert, but over the years I've learned what I like and what tastes good to me," Jones told Wine Spectator. "In my mid-20s, I had managers take me out to dinner and order wines and I had no clue what they were, but I developed a taste for good wine." Decades of European touring sharpened it further, in the food-and-wine cultures of Italy and France. Her stated go-tos are precise: crisp, dry whites — Grüner ...

Spam Musubi: Hawaii's Beloved After-School Snack — Aloha in a Handheld Meal

-
Image
  On a hot Hawaiian afternoon, running to the playground or the beach with friends after school, there was one thing every kid clutched in hand: Spam musubi . A salty slice of fried Spam, a block of sticky rice, and a belt of dark nori holding it all together. Simple, almost stubbornly so — but for children raised in Hawaii, no snack was more reliable, more filling, or more familiar. Add a rainbow shave ice after surfing or sweating through a game, and the whole island afternoon tasted like salt, sugar, and warm wind. From Wartime Ration to Island Icon How Spam Came to Hawaii Spam arrived in Hawaii the way it arrived everywhere in the Pacific: as a U.S. military ration in World War II. The islands, far from the mainland and under wartime restrictions — offshore fishing was curtailed, and after Pearl Harbor fresh meat and fish grew scarce — took the canned meat seriously. Where most places abandoned Spam once fresh food returned, Hawaii adopted it. Island families treated it lik...

Domaine d'Auvenay: The Tiny Estate Behind the World's Rarest White Burgundy

-
Image
  If Domaine Leroy is Lalou Bize-Leroy's public empire, Domaine d'Auvenay is her private garden. Hidden in the hills above Auxey-Duresses, the estate covers under four hectares scattered across some of Burgundy's humblest village appellations — plus a sliver of the grand cru Chevalier-Montrachet. From that sliver she makes a white wine in quantities of a few hundred bottles, which now trades for five figures and is spoken of by sommeliers the way birdwatchers speak of a species seen once in a lifetime. A Farm, Not a Brand Lalou bought the Auvenay property with her husband Marcel in the 1980s, long before the wines became mythical. There is no visitor center, no marketing department and effectively no public face. The vineyards are farmed biodynamically and plowed by horse; the cellar work is minimal; the yields are as punishingly low as at Leroy. Much of the production goes to a short list of loyal buyers who have stood by the domaine for decades, which is why bottles so ...

Tom Brady: The TB12 Diet and the Avocado Ice Cream That Fits His Rules

-
Image
  Tom Brady played elite football into his mid-forties, and his TB12 diet is one of the most talked-about eating plans in sports. It is mostly plant-based, highly restrictive, and built around a single idea: reduce inflammation wherever possible. What the TB12 Diet Excludes Brady's rules are strict. No white sugar, no white flour, no dairy, and no nightshade vegetables such as tomatoes, peppers, and eggplant, which he avoids for their potential inflammatory effects. Gluten is out, and most processed food is out with it. What remains is vegetables, whole grains like quinoa and brown rice, lean proteins, and healthy fats. The Favorite Food Workaround Brady's most famous dessert is avocado ice cream, made from an avocado base instead of dairy. It is the perfect symbol of his approach: he does not give up the idea of dessert, he rebuilds it to fit his rules. Hydration is the other pillar of the plan. He reportedly starts each day with water and electrolytes, and treats water in...

Red Velvet Cake: The $300 Recipe Legend, the Texas Dye Salesman, and America's Most Mythical Cake

-
Image
It is the most theatrical cake in America — crimson layers, white frosting, a whisper of cocoa — and almost everything about it is an argument. Was it invented at the Waldorf-Astoria? Is it Southern or New York? Was it originally red at all? The true history of red velvet is better than any of the legends, though the legends are pretty good too. Before It Was Red Velvet Meant Texture, Not Color In the Victorian era, "velvet" was a baker's term for a fine, soft crumb — velvet cakes were the delicate opposite of dense pound cakes. The red arrived by chemistry. Nineteenth-century cocoa was natural, not Dutch-processed, and its pigments — anthocyanins, the same compounds that color raspberries and roses — blush red in acid. Combined with buttermilk and vinegar, cocoa batter baked up a natural burgundy. Cakes in this family, like mahogany cake and devil's food, were reddish-brown long before anyone owned a bottle of food coloring. Food writer Stella Parks argues that r...

Peking Duck: Beijing's Lacquered Icon — The 72-Hour Craft Behind the Crispiest Skin on Earth

-
Image
  There is a moment in every great Peking duck dinner when the chef lifts the bird, mahogany and gleaming, and the room goes quiet. The skin shines like lacquer. It shatters like glass. It took three days to get there. Peking duck (Beijing kaoya) is not a roast; it is a discipline — air, sugar, wind, and fruitwood fire, in that order — and every step has a way to fail. That is precisely why, after six centuries, it remains the most famous dish in China. From Imperial Kitchens to Roast Duck Diplomacy Six Hundred Years of One Bird Roast duck was refined in the imperial kitchens of the Ming Dynasty, but the Peking duck we know was codified by two rival houses. Bianyifang traces its closed-oven technique to 1416: the duck roasts sealed away from direct flame, filled with a special soup so it roasts outside and simmers inside at once, emerging juicier but softer-skinned. Quanjude , founded in 1864 by poultry dealer Yang Quanren, pioneered the hung oven: ducks hang over open fruitw...

Koong Ten: Thailand's Dancing Shrimp — The Dish That Moves Before You Eat It

-
Image
  Scroll food videos long enough and you will meet it: a bowl of tiny translucent shrimp, twitching and leaping as lime juice hits them, while the diner tries to keep them on the plate. This is koong ten (กุ้งเต้น), literally "dancing shrimp" — a raw salad from Thailand's Isan region and neighboring Laos, and one of the most startling dishes in Southeast Asia. It is not a trick of editing. The shrimp really do dance. From the Mekong to the Market Stall An Isan Classic Isan, Thailand's northeast, is a cuisine built on the Mekong River and its tributaries: sticky rice, fiery som tam, grilled chicken, and raw preparations dressed in lime, fish sauce, and chili. Koong ten belongs to that family. The shrimp are not the tiger prawns of a Bangkok restaurant but tiny freshwater shrimp, barely larger than a sliver of onion, scooped live from tanks or river baskets at fresh markets and Isan restaurants. Vendors sell them from double-basket carts: seasonings on one side, a ...

Buddha Jumps Over the Wall: The Soup So Fragrant a Monk Abandoned His Meditation

-
Image
  There are difficult recipes, and then there is Fo Tiao Qiang — a soup that takes days, dozens of ingredients, and a sealed wine jar, and carries the most famous name in Chinese cooking: Buddha Jumps Over the Wall . The story goes that when the jar was opened, the aroma drifted to a nearby temple, where a vegetarian monk, meditating in discipline, caught the scent — and climbed over the wall to taste it. It is a legend, but like most legends about this dish, it undersells the labor. The True Story Behind the Name From an Official's Table to a Fuzhou Institution The dish began in 1870s Fuzhou, capital of Fujian, under a luckier name: Fu Shou Quan — "Full of Blessing and Longevity." An official's wife created it for a banquet honoring Zhou Lian, the provincial treasurer, simmering chicken, duck, pork, and seafood together in a Shaoxing wine jar. Zhou was so taken with it that his chef, Zheng Chunfa , was set to study the method. Zheng refined it — more seafood, les...

Biscuits and Gravy: The Southern Soul Food Breakfast That Smells Like Sunday Morning

-
Image
  Think of a Southern childhood and the first thing that comes back is often not a sight but a smell: butter, black pepper, and sausage drifting through the house on a Sunday morning. Biscuits and gravy — flaky buttermilk biscuits drowned in creamy white sausage gravy — is not just breakfast in the American South. It is love and comfort on a plate, the meal that gathered the whole family around the table before the week began. Calorie counting? In those days, that was not part of the recipe. Born in the Lumber Camps Sawmill Gravy: Fuel for Hard Work Biscuits and gravy in some form trace back to the Revolutionary War era, when staples were scarce, but the dish as we know it took shape in southern Appalachia in the late 1800s . It was working food. In lumber camps and sawmills, where a day of labor started before dawn, breakfast had to be cheap, filling, and calorie-dense — and the gravy earned its nickname there: sawmill gravy . Pork sausage drippings, flour, and milk, seasoned...

Passion Fruit Gel: The Tropical Gel That Makes Plates Glow

-
Image
A few glossy dots of passion fruit gel can turn a quiet plate into a tropical sunrise. Golden, glossy, and studded with jewel-like seeds, this gel delivers a bright punch of tart-sweet flavor in every drop, and because it holds its shape, it keeps looking sharp long after it hits the plate. This recipe shows you how to build a stable agar-based gel from real passion fruit pulp, plus how to plate it so it looks like it came from a fine-dining kitchen. What It Is A plating gel is a fluid sauce that behaves like a soft solid: it holds its shape on the plate yet melts on the tongue. Unlike a coulis, which spreads and soaks into the plate, an agar-set gel stays exactly where you pipe it. Passion fruit gel is made by setting sweetened passion fruit liquid with agar agar, chilling it into a firm jelly, and then blending that jelly back into a smooth, pipeable gel. The result is glossy and spoonable, with the full tropical fragrance of fresh passion fruit. If you stir a few whole seeds back ...
