Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lobster
- Forms the main body of the dish and supplies its flavour.
- Flour
- Thickens the milk into a smooth, spoonable sauce as its starch cooks.
- Butter
- Adds fat for richness and helps the flour blend smoothly.
- Milk
- Serves as the liquid base that the flour thickens into a sauce.
- Breadcrumbs
- Form a crisp topping that browns in the oven.
The step that matters
Stirring the flour mixture into boiling milk. Flour starch must be dispersed evenly as it hits the hot liquid. Stirring prevents lumps and lets the starch swell and thicken the sauce uniformly.
Swap the onion
How well each one fits the dish's main ingredients (lobster, flour, butter, mustard, milk, pepper):
- Shallotfits better
- Lettucefits better
- Horseradishfits better
- Onionthe original
Fit is the average pairing score against lobster, flour, butter, mustard, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
