Milk and sugar barely smell alike, yet cooks put them together in 77,875 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
Provides the base liquid, protein, and milk fat that give the mixture its body.
Water
Dilutes the milk so its protein and mineral content is lower and closer to infant needs.
Cream
Adds extra milk fat for a richer, softer mouthfeel.
Sugar
Adds sweetness and a mild flavor that makes the mixture more palatable.
Lactose
Serves as a sugar substitute that is milk-derived and suited to very young children.

The step that matters

Steam sterilize for twenty minutes. Milk-based mixtures support rapid bacterial growth, so the full sterilizing time must be held to kill microbes and keep the bottles safe to store and feed.
