Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raspberries
- Provide the main fruit flavor, tartness, and bright color at the centre of the tart.
- White sugar
- Sweetens the filling and helps it thicken as it cooks with the cream.
- Cream
- Adds richness and fat, giving the filling a smooth, soft texture.
- Egg whites
- Whipped to stiff peaks, they lighten the filling and add airy structure.
- Flour
- Thickens the cream mixture as it cooks, giving it body and stability.
The step that matters
Cook the cream mixture until thickened. Flour thickens only when the mixture is heated enough for its starch to swell. Undercooked filling stays runny and may not hold its shape once the egg whites are folded in and the tart is cut.
