Why it works: Cinnamon and peach match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 625 recipes. Both carry methyl cinnamate, which smells strawberry. The science ↓

Soft Custards

Ingredients

Directions

  1. Boil the milk with cinnamon or peach leaves if desired in a saucepan.

  2. Heat a pitcher gradually in a kettle of boiling water.

  3. Pour the boiling milk into the heated pitcher.

  4. Add sugar to the milk and stir until dissolved.

  5. Stir in the well-beaten eggs slowly.

  6. Continue stirring in one direction until the mixture thickens.

  7. Remove from heat and pour into cups or a cold pitcher to prevent hardening.

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

What each ingredient does

Eggs
Set the custard as they cook, thickening the liquid into a soft, spoonable texture.
Milk
Forms the liquid base that the eggs thicken, giving the custard its body.
Cream
Adds richness and fat, producing a smoother, silkier mouthfeel.
Sugar
Sweetens the custard and dissolves into the liquid base.

The step that matters

Continue stirring in one direction until the mixture thickens. Egg proteins set when heated, and if the custard gets too hot or is stirred unevenly it can curdle or harden in lumps. Gentle, steady stirring keeps the proteins evenly thickened into a smooth custard.

Swap the cinnamon

The recipe marks cinnamon as optional. How well each one fits the dish's main ingredients (milk, cream, egg, sugar, peach):

  1. Cinnamonthe original
  2. Nutmegfits about as well
  3. Gingerfits less well
  4. Peppermintfits less well

Fit is the average pairing score against milk, cream, egg, sugar, peach. Candidates are from the same food group and used in at least 100 recipes.
