Why it works: Lemon and cinnamon match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 7,950 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Custard Cream
Ingredients
Directions
Infuse the cream
Boil the cream with the lemon peel, cinnamon, and sugar.
Beat the egg yolks in a separate bowl.
Gradually mix the egg yolks with the cream mixture.

Cinnamon and sugar barely smell alike, yet cooks put them together in 30,779 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
- Egg yolks
- Thicken the custard as their proteins set on gentle heat, giving it body.
- Cream
- Provides richness and fat, giving the custard a smooth, creamy texture.
- White sugar
- Adds sweetness and balances the richness of the cream and yolks.
- Lemon peel
- Adds bright citrus aroma that infuses into the hot cream.
- Cinnamon
- Adds warm spiced aroma that infuses into the hot cream.
The step that matters
Remove from heat the moment it begins to boil. Egg yolks thicken as their proteins set, but if the custard gets too hot it can curdle or turn grainy. Stirring gently and stopping at the first boil keeps it smooth.

- Figfits about as well
- Lemonthe original
Fit is the average pairing score against cream, cinnamon, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
