Name: Fruit Biscuit
Ingredients: 1 cup sugar; 1 cup butter; 1 cup seedless raisins, chopped; 1 egg; 3 teaspoons baking powder; vanilla extract, to taste; lemon extract, to taste

Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

Fruit Biscuit

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

Preheat the oven to 350°F (175°C).

Make the dough

In a bowl, cream together the sugar and butter.
Add the chopped raisins, egg, baking powder, vanilla, and lemon extract; mix well.
Roll out the dough and cut into shapes with a biscuit cutter.

Bake

Place on a greased baking sheet lined with parchment paper.
Bake for 10-12 minutes or until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter: Creaming with sugar traps air and gives the biscuits a tender, rich texture.
Sugar: Creamed with butter, it adds sweetness and helps the biscuits brown.
Egg: Binds the dough and adds structure and moisture to the biscuits.
Baking powder: Releases gas in the oven, helping the biscuits rise and become light.
