Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Provide the main meaty filling, becoming tender when parboiled and chopped finely.
- Cream
- Adds moisture and richness, and with the flour forms a smooth, thick binding sauce.
- Flour
- Thickens the butter and cream into a smooth base that holds the filling together.
- Egg yolk
- Enriches the filling and helps bind it so the croquettes hold their shape.
- Eggs
- Form a coating that helps the bread crumbs stick and brown during frying.
- Mushrooms
- Add moisture and savory flavor to the filling, bulking out the sweetbreads.
The step that matters
Allow the mixture to cool before shaping. A warm, loose filling will not hold its shape and may split or slump when dipped and fried. Cooling lets the cream and flour mixture firm up so the croquettes stay intact.
Swap the onion
How well each one fits the dish's main ingredients (butter, flour, pepper, cream, lemon, mushroom, egg):
- Spinachfits better
- Shallotfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against butter, flour, pepper, cream, lemon, mushroom, egg. Candidates are from the same food group and used in at least 100 recipes.
