Why it works: Ham and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,536 recipes. Both carry 2-acetyl-1-pyrroline, which smells popcorn, roasted. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Form the bulk of the filling and give the croquettes their body.
- Thick white sauce
- Binds the minced ingredients together so the mixture holds its shape.
- Bread crumbs
- Form a crisp outer crust that browns when fried.
- Ham
- Adds savory, salty flavor to the filling.
- Anchovies
- Contribute a deep savory note to the filling.
- Cooked mushrooms
- Add moisture and earthy flavor to the filling.
The step that matters
Letting the filling cool before shaping. A warm, loose mixture is soft and sticky, so the croquettes can slump or split. Cooling lets the white sauce firm up so the portions hold their shape and the coating stays intact during frying.
