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 ↓

Ingredients
Directions
Prepare the cases
Divide the potato pastry into 8 portions, shape into balls, and flatten each slightly.
Coat each with egg and breadcrumbs, smooth with a knife, and coat again.
Mark a ring on top of each with a small cutter.
Fry in hot fat until golden, then remove the tops and scoop out some potato.
Make the filling
Melt the butter in a pan, add flour, then gradually stir in milk until boiling.
Add the shrimps, lemon juice, and seasonings; heat through.
Fill and serve
Fill the potato cases with the mixture, replace the tops, and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potato pastry
- Forms the crisp outer case that holds the filling when fried.
- Butter
- Enriches the white sauce and carries flavour through the filling.
- Milk
- Forms the liquid base of the sauce, thickened with flour to a coating consistency.
- Cream
- Adds richness and a smoother, silkier texture to the filling.
- Shrimps
- Provide the main seafood flavour and tender texture in the filling.
The step that matters
Frying the cases until golden. Fat must be hot enough to crisp and brown the coated pastry quickly; if it is too cool the coating absorbs oil and turns greasy and pale.
Swap the mace
How well each one fits the dish's main ingredients (potato, shrimp, fish, pepper, butter, milk, cream):
- Parsleyfits better
