Why it works: Mushroom and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
Croquettes De Viande
Ingredients
Directions
Prepare
Remove excess fat, skin, and gristle from the meat and mince it finely, including the ham or tongue and mushrooms.
Peel and finely chop the onion, then fry it in the butter until softened.
Add the flour to the onion and stir for a few minutes over the heat.
Make the mixture
Mix in the minced meat, season with salt, pepper, and herbs, then moisten with stock and heat thoroughly.
Stir in the yolks of the eggs and continue stirring until the mixture thickens.
Transfer the mixture to a dish and let it cool.
Shape and fry
Divide into even portions and shape into cork or ball shapes.
Dip each shape in beaten egg, roll in breadcrumbs, and fry in hot fat until golden brown.
Drain and serve garnished with fried parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold meat
- Forms the bulk of the croquettes and gives them their savoury, meaty body.
- Eggs
- Yolks thicken the mixture when stirred in, and beaten egg helps the breadcrumbs stick.
- Flour
- Cooked with the butter and onion, it helps thicken the mixture so it holds its shape.
- Butter
- Softens the onion and adds richness and flavour to the mixture.
- Breadcrumbs
- Form a crisp, golden outer coating when fried.
The step that matters
Stirring in the egg yolks. The yolks must be stirred in and the mixture kept moving so it thickens evenly. Egg proteins set with heat, so if the mixture is overheated or left still it can curdle or turn lumpy, and cooling it fully before shaping lets the portions hold together.
Swap the onion
How well each one fits the dish's main ingredients (meat, ham, mushroom, butter, flour, pepper, egg):
- Shallotfits better
- Asparagusfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against meat, ham, mushroom, butter, flour, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
