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 ↓
Richer Custard
Ingredients
Directions
Flavor the milk
Boil the milk with lemon peel and cinnamon.
Once the milk is flavored, sweeten it to taste.
Make the custard
In a bowl, mix the cream and beaten egg yolks.
Pour the milk into the cream mixture, stirring well.
Simmer the custard until it thickens, stirring continuously in one direction.
If desired, use 1 quart of cream instead of milk for a richer custard.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Yolks thicken the custard as their proteins set with gentle heat, giving a smooth body.
- Milk
- Forms the liquid base that the yolks and cream thicken into custard.
- Cream
- Adds fat for richness and a smooth, velvety texture.
- Sugar
- Adds sweetness that balances the rich dairy and egg flavors.
The step that matters
Simmering the custard. Egg yolks thicken as their proteins set with heat, but if the custard gets too hot it can curdle and turn grainy. Keep the heat gentle and stir steadily so the yolks cook evenly.
