Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Rissoles and Croquettes
Ingredients
Directions
Prepare the rissole
Prepare the rissole mixture hours before and let it set in a cold place until firm.
Divide the mixture into equal parts and roll each into a small ball or oval, ensuring the surface is crack-free.
Brush each ball with beaten egg.
Coat each ball with breadcrumbs.
Fry the coated balls in deep fat until golden brown.
Make the croquettes
Make a short paste with butter or lard and flour.
Add a little egg to bind the paste.
Roll the paste to ⅛ inch thick.
Cut the paste into squares or rounds about 2½ inches across.
Place a small teaspoonful of ragout or mince mixture on each piece.
Wet the edges of each piece.
Fold over the piece and press to seal.
Brush each piece with beaten egg.
Roll each piece in crushed vermicelli.
Fry the vermicelli-coated pieces until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rissole mixture
- Forms the main filling and sets firm so the balls hold their shape when fried.
- Breadcrumbs
- Form a crisp, golden coating that protects the rissoles during deep frying.
- Butter or lard
- Adds fat to the paste, making it short and tender when baked or fried.
- Flour
- Gives the paste its structure so it can be rolled, cut and sealed.
- Beaten egg
- Acts as a glue for breadcrumbs and vermicelli and browns the surface.
- Vermicelli
- Adds a crunchy, golden outer crust to the croquettes when fried.
The step that matters
Sealing the croquette pieces. If the edges are not wet and pressed firmly, the paste will not stick together, and the filling can leak out during frying.
