Make the base
In a saucepan, brown the butter and flour over medium heat.
Add the beef stock and stir until thick and smooth.

Serve
Serve with tomato sauce or a good brown sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the butter and stock into a binding paste that holds the croquettes together.
- Butter
- Adds richness and fat, and browns with the flour to give a nutty flavour.
- Beef stock
- Supplies the liquid that cooks the flour into a thick, smooth base.
- Boiled rice
- Adds bulk and body, helping the mixture hold its shape when cooled.
- Egg
- Coats the shaped croquettes so the breadcrumbs adhere and form a crust.
- Ham
- Provides the main savoury, meaty flavour of the filling.
The step that matters
Cool the mixture fully before shaping. A warm, loose mixture is soft and sticky, so croquettes can break or collapse in the hot oil. Cooling lets the starch set so the shapes hold together during frying.
Swap the onion
