  2. Stir this mixture into the scalding milk.

  3. Cook in a double boiler for 30 minutes.

Prepare the raisins

    Shared aroma: decanoic acid (acides aroma).

Flour and milk 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

Flour
Its starch thickens the milk into a smooth gruel as it cooks.
Milk
Forms the liquid base, and its proteins and sugars add body and flavor as it cooks.
Raisins
Add concentrated sweetness and a soft, chewy texture.

The step that matters

Mixing the flour into the milk. Flour mixed directly into hot milk forms lumps as its starch swells unevenly. Blending it first with cold milk disperses the starch, so it thickens smoothly when stirred into the scalding milk.
