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

What each ingredient does

Egg yolks
Thicken the custard and add richness as they set gently with heat.
Milk
Forms the liquid base that the egg yolks set into a smooth custard.
Cream
Adds fat for a richer, softer texture and smoother mouthfeel.
Isinglass
Gelatin-like setting agent that helps the custard firm up as it cools.

The step that matters

Heat gently without boiling. Egg yolks thicken through gentle heat; if the custard boils, the proteins curdle and it turns grainy or watery. Stirring constantly over low heat spreads the heat evenly and prevents scorching on the bottom.

Swap the lemon

How well each one fits the dish's main ingredients (milk, cinnamon, egg, tea, cream, almond, brandy):

  4. Lemonthe original

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