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
Prepare

Return the mixture to the heat and cook until thickened, stirring constantly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard as they set when gently heated, giving it body.
- Cream
- Adds richness and fat, giving the custard a smooth, soft texture.
The step that matters
Adding the hot mixture to the eggs. Pouring the boiling liquid into the eggs too quickly can scramble them. Adding it slowly while stirring gently warms the eggs so they thicken smoothly.
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.
