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 that gives the croquettes their body and flavour.
- Milk
- Forms the smooth, thickened base that binds the filling together.
- Egg yolks
- Add richness and help set the filling so it holds its shape.
- Flour
- Thickens the milk with the butter, giving the filling structure so it can be shaped.
- Butter
- Adds fat and richness to the filling and its smooth texture.
The step that matters
Scalding the milk. Milk scorches easily on direct heat, and scorched proteins taste bitter and stick to the pan. Heating gently and stirring keeps the milk smooth and ready to thicken with the butter-flour mixture.
Swap the onion
How well each one fits the dish's main ingredients (milk, egg, butter, flour, parsley, pepper, nutmeg):
