Why it works: Apple and milk are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 4,104 recipes. Both carry 4-heptenal, which smells creamy, biscuit. The science ↓
Apple Fool
Ingredients
Directions
Prepare the apples
Remove the cores from the apples and cook them until soft. Beat the cooked apples into a pulp and let them cool.
Make the custard
Mix Goodall's custard powder with 2 tablespoons of tinned milk dissolved in 1 pint of water to make a custard.
Combine and serve
Stir the custard into the cooled apple pulp.
Serve in glass dishes with rusks or finger biscuits on the side.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Cooked and beaten into a pulp, they form the fruity base of the fool.
- Goodall's custard powder
- Thickens the liquid into a custard that gives the fool its creamy body.
- Tinned milk
- Adds richness and creaminess to the custard.
The step that matters
Let the apple pulp cool before adding the custard. Custard thickens as it cools, and adding it to hot pulp can cause it to curdle or thin out. Cooling the pulp first keeps the custard smooth and lets the fool set to a light, creamy texture.
