Why it works: Cinnamon and lemon 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 ↓
Baked Custard
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the custard
Boil the cream and milk with cinnamon and lemon peel until combined.
Let the mixture cool.
In a bowl, mix the cooled mixture with the egg yolks and sugar.
Bake
Line a pie plate with pastry and pour the custard mixture in.
Bake at 350°F (175°C) for 15 minutes.

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
- Proteins set as the custard heats, thickening the liquid into a sliceable custard.
- Cream
- Adds fat for a rich, smooth texture and a full mouthfeel.
- Milk
- Forms the liquid base that the eggs thicken, keeping the custard moist.
- Sugar
- Adds sweetness and balances the richness of the cream and yolks.
The step that matters
Bake until just set. Egg proteins set as the custard heats. Too much heat tightens them further, so the custard can curdle, weep liquid, or turn grainy. Remove it once the centre barely wobbles.
Swap the lemon
How well each one fits the dish's main ingredients (cream, milk, cinnamon, egg, sugar):
- Vanillafits better
- Raisinfits better
- Figfits better
- Lemonthe original
Fit is the average pairing score against cream, milk, cinnamon, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
