Why it works: Egg and sugar are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Bread-and-butter Pastry
Ingredients
Directions
Prepare the pastry
Roll out the puff pastry to ⅙ inch thick and give it seven turns.
Stamp out 18 circular pieces, 1½ inches in diameter.
Place the pieces on a wet baking sheet.
Stamp out smaller pieces, 1 inch in diameter.
Cut out the centers of the smaller pieces.
Wet the surface of the larger pieces.
Place the smaller pieces on top of the larger pieces.
Press down gently.
Bake and finish
Brush the tops with beaten egg.
Bake until light golden.
Sprinkle fine sugar over them.
Return to the oven for 1-2 minutes.
Use a salamander to give a glossy finish before serving.
Fill with preserved cherries, greengage jam, or currant jelly before serving.

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.
-

Shared aroma: 2-nonenal (fatty, green).

Sugar and currant barely smell alike, yet cooks put them together in 12,256 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
- Puff pastry
- Its laminated layers of butter and dough puff into flaky, airy structure when baked.
- Egg
- Beaten egg brushed on top promotes browning and a glossy, golden surface.
- Preserved cherries, greengage jam, or currant jelly
- Adds sweetness and fruity acidity inside the pastry rings.
The step that matters
Keep the top ring lightly pressed and the pastry edges unsealed. Pressing too hard or wetting the wrong areas can squash the layers so they cannot rise, leaving dense pastry instead of flaky, well-defined rings.
Swap the currant
How well each one fits the dish's main ingredients (egg, sugar):
- Vanillafits better
- Raisinfits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
