Why it works: Cinnamon and vanilla match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 5,287 recipes. Both carry 4-methoxybenzaldehyde, which smells sweet, anise. The science ↓
A German Custard Pudding-sauce
Ingredients
Directions
Make the custard base
In a saucepan, gently boil the milk or milk and cream with lemon rind, cinnamon, vanilla bean, and sugar until flavored.
Strain the mixture and slowly pour it into the beaten egg yolks mixed with flour, salt, and cold milk. Stir quickly as you add the milk mixture.
Thicken the sauce
Return the sauce to the saucepan and whisk or stir rapidly until it thickens and looks creamy.
Hold the saucepan over the heat, but do not place it directly on the fire.

Vanilla and sugar barely smell alike, yet cooks put them together in 35,032 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 sauce as they set with gentle heat, giving it a creamy body.
- Milk
- Forms the liquid base that carries the flavors and becomes the sauce.
- Sugar
- Sweetens the sauce and balances the richness of the yolks and milk.
- Flour
- Stabilizes the custard so it is less likely to curdle during thickening.
The step that matters
Hold the saucepan over the heat, but do not place it directly on the fire. Egg yolks scramble when exposed to direct, intense heat. Gentle indirect heat, combined with constant stirring, lets the custard thicken smoothly without curdling.
