Why it works: Almond and flour are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Orange Heart Biscuits
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the flavourings
Combine powdered sugar and egg yolks in a bowl.
Pound preserved orange peels into a fine paste. Pound sweet and bitter almonds very fine.
Mix the almond paste with orange flower water.
Add the almond mixture to the bowl with sugar and egg yolks.
Make the batter
Beat the 4 eggs until light and fluffy in a separate bowl.
Add the beaten eggs to the mixture.
Mix everything well with a wooden spoon until the batter is light and puffy.
Gently fold in the sifted flour until just combined.
Bake and serve
Grease the heart-shaped molds with butter and fill them with the batter.
Dust the tops with powdered sugar before baking.
Bake in a quick oven at 400°F (200°C) until light and golden.
Remove from the molds while hot.

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.

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
- Egg yolks
- Add richness and structure, setting the batter as they cook.
- Eggs
- Whipped to trap air, giving the biscuits a light, puffy crumb.
- Sweet and bitter almonds
- Provide body and nutty flavour to the batter.
- Flour
- Provides structure so the biscuits hold their shape after baking.
- Powdered sugar
- Sweetens the batter and helps it brown on the surface.
- Preserved orange peels
- Supply the characteristic citrus aroma and flavour.
The step that matters
Fold in the flour gently. Overmixing after adding flour develops gluten and deflates the whipped eggs, making the biscuits dense instead of light.
Swap the orange
How well each one fits the dish's main ingredients (sugar, egg, almond, flour, butter):
- Raisinfits better
- Vanillafits better
- Figfits better
- Orangethe original
Fit is the average pairing score against sugar, egg, almond, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
