Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Radish Tart
6–8Ingredients
Directions
Make the shell
Preheat the oven to 425°F (220°C).
Sift and measure the flour into a bowl.
Cut in the butter until the particles are coarse.
Stir in half of the cheese.
Pour in ¼ cup of the cream and toss the mixture with a fork until all parts are moistened.
Turn the dough into a 9‑inch round pie pan.
With floured fingers, press the mixture into the bottom and sides of the pan, then prick the shell with a floured fork.
Bake the pie shell for 10–12 minutes.
Cool the shell on a wire rack.
Fill and bake
Lower the oven temperature to 375°F (190°C).
Sprinkle the remaining cheese evenly over the bottom of the cooled pie shell.
Beat together the egg yolks, ¾ cup of cream, and the salt.
Pour the egg mixture over the cheese.
Place the radish slices evenly over the top of the pie.
Bake for 20–25 minutes, or until set.
Remove the pie from the oven, cut it into wedges, and serve it hot.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- All-purpose flour
- Forms the structure of the crust once mixed with butter and liquid.
- Cold butter
- Cut into the flour to create flaky, tender layers in the crust.
- Cheese
- Melts into the crust and custard, adding savory richness and flavor.
- Heavy cream
- Adds moisture and fat, giving the custard a smooth, rich texture.
- Egg yolks
- Sets with gentle heat to bind the custard and give it a creamy body.
The step that matters
Bake the custard until just set. Overbaking causes egg proteins to tighten and weep, leaving the custard grainy and watery. Bake only until the center is set and no longer liquid.
