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 ↓
Pineapple Custards
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.
Prepare
Preheat oven to 350°F (175°C).
Beat eggs until light and fluffy.
Make the custard
In a bowl, mix butter, sugar, corn starch (or flour), and sweet milk.
Fold in grated pineapple.
Combine egg mixture with other ingredients and pour into custard cups.
Bake
Bake in preheated oven until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard into a tender structure as they cook and provide richness.
- Butter
- Adds fat for a rich, tender texture and smooth mouthfeel.
- Sugar
- Adds sweetness and helps the custard brown lightly at the edges.
- Corn starch or flour
- Thickens the custard so it holds its shape when baked.
- Grated pineapple
- Adds moisture, tart fruit flavor, and aroma to the custard.
The step that matters
Bake until set. Eggs firm as their proteins coagulate with heat. Pulling the custards too early leaves them runny, while overbaking makes them dry and rubbery.
Swap the pineapple
How well each one fits the dish's main ingredients (egg, butter, sugar, corn, milk):
- Vanillafits better

- Figfits better
- Pineapplethe original
Fit is the average pairing score against egg, butter, sugar, corn, milk. Candidates are from the same food group and used in at least 100 recipes.
