Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Egg Croquets
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the filling
Chop the hard-boiled eggs and ham finely.
In a saucepan, melt the butter over medium heat.
Stir in the flour and cook for 1 minute.
Gradually add the milk, stirring until the mixture thickens.
Fold in the chopped eggs and ham.
Shape and coat
Shape the mixture into croquettes.
Roll each croquette in cracker crumbs, then in the beaten egg, and again in the cracker crumbs.
Fry
Fry the croquettes in hot lard or butter until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Mixed with butter to form a roux that thickens the milk into a binding sauce.
- Butter
- Melts with the flour to form the roux and adds richness to the filling.
- Milk
- Hydrates the flour and, as it heats, thickens into a sauce that holds the filling together.
- Hard-boiled eggs
- Provide the main filling, setting firm in the sauce and giving body to the croquettes.
- Beaten egg
- Forms a binding coat that helps the cracker crumbs adhere before frying.
- Cracker crumbs
- Form a crisp, browned outer crust when fried.
The step that matters
Thickening the milk into the roux. Adding the milk too quickly or without steady stirring can leave lumps. The filling must be thick enough to hold its shape, or the croquettes may fall apart in the coating and frying.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
