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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the filling as they set, and beaten whites form the light frosting.
- Flour
- Starch thickens the milk and sugar mixture so the filling holds its body.
- Milk
- Provides the liquid base and richness for the filling.
- White sugar
- Sweetens the filling and balances the sharpness of the lemon.
- Lemon
- Adds acidity and fresh citrus aroma to the filling.
- Powdered sugar
- Sweetens the frosting and helps the beaten whites hold together.
The step that matters
Return to oven until slightly brown. The sugar-rich frosting browns quickly once heated, because sugars and proteins caramelize and brown faster at higher heat. Watch it closely, since a few extra minutes can turn it dark or bitter.
