Why it works: Vanilla and chocolate are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Jellied Cookies
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Separate the eggs and beat the yolks until creamy.
Add sugar and beat well.
Mix in vanilla, then pour in cold water and flour alternately, adding the baking powder sifted with the flour.
Fold in the beaten egg whites gently.
Bake and fill
Bake at 400°F (200°C) until done, similar to "Chocolate Squares."
Once cooled, put jelly between the cookies and dip in chocolate, caramel, or white icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks add richness and the whipped whites lighten the batter for a tender structure.
- Flour
- Provides the main structure that sets as the cookies bake.
- Sugar
- Adds sweetness and helps the beaten yolks become creamy and stable.
- Baking powder
- Releases gas during baking so the cookies rise and become lighter.
The step that matters
Folding in the beaten egg whites. Egg whites hold air that gives lift. Folding gently keeps that air in the batter; vigorous stirring deflates it and leaves the cookies dense.
