Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Croquettes of Potatoes
Ingredients
Directions
Prepare the potatoes
Boil potatoes until tender, then drain and dry them.
Pass the potatoes through a wire sieve into a bowl.
Make the mixture
In a saucepan, heat the butter and milk until hot, then add the potatoes.
Season with cayenne or black pepper and coarse sea salt, then mix in the egg until well combined.
Transfer the mixture to a plate and let it cool.
Shape, coat and fry
Once cool, lightly flour a board and shape the mixture into balls and cork-shaped pieces.
Coat each piece in egg and then in bread crumbs, reshaping as necessary.
Heat oil in a frying pan and fry the croquettes until golden brown.
Drain on kitchen paper and serve on a folded doily with fried parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the croquette, giving a soft, starchy interior once cooked.
- Butter
- Adds richness and fat, making the mashed potato smoother and more tender.
- Milk
- Adds moisture so the potato mixture becomes soft and easy to shape.
- Egg
- Binds the mixture together and forms a coating that helps the crumbs stick.
- Bread crumbs
- Form a crisp, golden outer crust when the croquettes are fried.
The step that matters
Let the mixture cool before shaping. A warm, soft potato mixture is too sticky to hold its shape and can break apart in the coating and oil. Cooling lets the starch firm up so the pieces keep their form.
