Why it works: Milk and butter 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 ↓
Tapioca Pudding
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the pudding
Wash the tapioca and combine it with the milk in a pot.
Add the grated lemon rind, butter, and sugar to taste.
Boil the mixture for 1 hour.
Beat the eggs well and add them to the mixture.
Bake and serve
Pour the mixture into a baking dish and bake at 350°F (175°C) for 45 minutes.
Serve with sauce, or sugar and cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tapioca
- Its starch swells during cooking and thickens the milk into a creamy body.
- Milk
- Forms the liquid base that the tapioca cooks in and the custard sets from.
- Eggs
- Set when heated, binding the pudding and giving it a soft, custard-like firmness.
- Butter
- Adds fat for richness and a smoother, rounder mouthfeel.
- Lemon rind
- Contributes aromatic citrus oils that brighten the flavour of the pudding.
The step that matters
Adding the beaten eggs. Eggs thicken when heated, but if the mixture is very hot when they go in, they can scramble into small lumps. Beat them well and stir them through the mixture evenly so they combine smoothly and set into a uniform custard.
Swap the lemon
How well each one fits the dish's main ingredients (milk, butter, sugar, egg):
