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 ↓
Mixed Vegetable Ring
Ingredients
Directions
Prepare the vegetables
Pre-heat oven to 200C / 400F / Gas 6.
Melt 25 g (1 oz) of the butter in a large saucepan.
Lightly fry the onion and mushrooms for 5 minutes, until softened.
Add the courgettes, aubergine and red pepper and cook for 5 minutes, stirring occasionally.
Add the tomatoes.
Make the choux-style base
Melt the remaining butter in a saucepan with the milk, then bring to a boil.
Remove the pan from the heat, tip in all the flour and beat thoroughly with a wooden spoon.
Allow to cool slightly, then beat in the eggs, a little at a time.
Stir in the walnuts.
Bake and serve
Pipe or spoon around the edge of a well-greased 900 ml (1 pint) ovenproof serving dish.
Fill the centre with the vegetables.
Bake for 35-40 minutes, until the pastry is risen and golden.
Sprinkle with the cheese, return to the oven until the cheese has melted.
Serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the flour paste and help the base puff and set as it bakes.
- Plain flour
- Forms the starch-and-egg paste that gives the risen, golden edge its structure.
- Butter
- Adds richness and fat that helps the paste cook to a golden colour.
- Milk
- Moistens the paste and adds richness as it heats and thickens.
- Cotswold cheese
- Melts over the vegetables to add flavour and a creamy topping.
The step that matters
Beating the eggs into the flour paste. Adding eggs while the paste is still hot can scramble them, so let it cool slightly and add them a little at a time. Beating gradually gives a smooth, glossy paste that rises evenly in the oven.
Swap the onion
How well each one fits the dish's main ingredients (butter, mushroom, pepper, tomato, milk, flour, egg):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against butter, mushroom, pepper, tomato, milk, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
