Why it works: Cream and vanilla are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 12,301 recipes. Both carry 2-nonanone, which smells fruity, floral. The science ↓

Ingredients
Directions
Make the base
Mix the cream and water together in a saucepan.
Dissolve the saccharin in the mixture.
Heat the mixture until it begins to boil.
Thicken the custard
In a separate bowl, beat the eggs.
Slowly add the hot mixture to the beaten eggs, stirring constantly.
Return the mixture to the saucepan and cook over low heat until thickened.

Cream and vanilla barely smell alike, yet cooks put them together in 12,301 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
- Eggs
- Proteins set as they heat, thickening the liquid into a custard.
- Cream
- Adds fat and richness, giving the custard a smooth, creamy texture.
- Saccharin
- Provides sweetness without adding sugar.
- Vanilla
- Adds aroma and flavor to the custard.
The step that matters
Slowly add the hot mixture to the beaten eggs. Adding hot liquid to eggs gradually, while stirring constantly, warms the eggs gently so they thicken smoothly instead of scrambling into lumps.
Swap the vanilla
How well each one fits the dish's main ingredients (cream, egg):
- Vanillathe original
- Raspberryfits about as well
- Strawberryfits less well
- Coconutfits less well
Fit is the average pairing score against cream, egg. Candidates are from the same food group and used in at least 100 recipes.
