Why it works: Egg and flour are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Bloomin' Onion
Ingredients
Directions
Prepare the onion
Select a well‑rounded onion.
Peel the outer skin off.
Leave the root intact and cut off any hanging roots.
Using a small, sharp knife, divide the onion into four sections by making two cuts crosswise, beginning at the top and cutting toward the root, stopping about ½ inch away. Cut each section twice.
Place the onion in a bowl of enough boiling water to cover it and leave for 5 minutes. The sections, or petals, will begin to open.
Remove the onion from the water and immerse it in ice water, which will further the opening. Drain well by turning upside down on a paper towel.
Coat the onion
Put flour into a paper bag, add the onion, and shake gently to coat with flour.
Roll the floured onion in beaten egg to cover.
Put cracker crumbs or coating in a bag, add the onion, and shake gently to coat.
Refrigerate for 1 hour before deep frying in oil until golden brown, 3 to 5 minutes.
Nutrition, whole recipe (rough)
Counts 4 of 5 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 4 portions
| Ingredient | Portion assumed | kcal |
|---|---|---|
| Flour | 1 cup (125g) all-purpose | 455 |
| Egg | 1 large egg (50g) | 78 |
| Cracker | 5 saltine crackers (15g) | 66 |
| Onion | 1 medium (110g) | 44 |
| Water | not in our table | 0 |

Shared aroma: 2,4-decadienal (seaweed).
Egg and flour barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Forms the main body; its layers separate into petals when cut and blanched.
- Flour
- Dry coating that helps the beaten egg adhere to the onion.
- Eggs
- Wet binder that holds the cracker crumbs to the onion.
- Cracker crumbs
- Crisp outer coating that browns in the hot oil.
The step that matters
Refrigerate before deep frying. Chilling the breaded onion firms the coating so it adheres and stays crisp in the hot oil instead of sliding off or turning greasy.
Swap the onion
How well each one fits the dish's main ingredients (egg, flour):
- Arrowrootfits better
- Chivefits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against egg, flour. Candidates are from the same food group and used in at least 100 recipes.
