Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Ice Cream
Ingredients
Directions
Make the custard
Boil 1 quart of milk with the sugar, stirring until dissolved.
In a separate bowl, beat the egg yolks with a fork.
Add the beaten yolks to the warm milk.
When the milk boils, stir in the moistened flour until thickened.
Finish the mixture
Pour the mixture over the beaten egg whites, beating rapidly.
Add the remaining quart of milk and cool the bowl in cold water.
If using sherry wine for flavor, add it when the mixture begins to freeze.

Milk and flour barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base of the custard and gives the ice cream its creamy body.
- Sugar
- Sweetens the mixture and lowers its freezing point, keeping the frozen result softer.
- Flour
- Thickens the milk mixture as its starch swells when heated and boiled.
- Egg yolks
- Thicken the custard as they cook and add richness and smoothness.
- Egg whites
- Beaten into foam, they add lightness and an airy texture.
The step that matters
Stir in the moistened flour once the milk boils. Starch only thickens properly when it is fully hydrated and heated to boiling. Adding it too early or dry can leave lumps, and stopping short of a boil leaves the custard thin.
