Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Thickens the liquid as its starch swells and sets during heating.
New milk
Forms the liquid base and adds body and a soft, creamy texture.
Lemon peel
Adds a bright, fragrant citrus aroma to the drink.
Sweetener
Adds sweetness to balance the flavour.

The step that matters

Blend the flour fully into the cold water first. Flour starch clumps when it meets hot liquid directly. Mixing it smooth in cold water first lets the starch disperse evenly, so the caudle thickens without lumps.

Swap the lemon

How well each one fits the dish's main ingredients (flour, milk):
