  6. Remove from heat and let cool.

  7. Flavor the mixture.

  8. Pour it into a glass dish.

  9. Refrigerate until very cold.

  2. Gradually beat in 3 tablespoons of sugar and 2 tablespoons of currant jelly.

  3. Spread the meringue over the top of the custard.

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

What each ingredient does

Eggs
Yolks thicken the custard as they set, and whites whip into the airy meringue topping.
Milk
Forms the liquid base of the custard, which thickens as the egg proteins set.
Sugar
Sweetens the custard and helps stabilize the whipped egg white meringue.
Currant jelly
Adds fruity sweetness and tartness to the meringue, and flavor to the dish.

The step that matters

Cook the custard until thickened, without overheating. Egg yolks thicken as their proteins set with gentle heat. If the custard gets too hot, the eggs scramble and curdle, so the custard turns grainy. Stirring constantly and tempering the eggs with warm milk first helps prevent this.

Swap the currant

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

  1. Vanillafits better
  2. Figfits better
  3. Raisinfits better
  4. Currantthe original

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