Why it works: Sugar and cocoa powder are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 2,920 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Chocolate Kisses
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Warm the sugar and cocoa mixture together.
Drop the mixture in round shapes onto greased pans.
Bake in a slow oven at 300°F (150°C) until dry.

What each ingredient does
- Sugar
- Provides sweetness and bulk, and helps the kisses set and dry into a crisp shell.
- Egg whites
- Add structure and lift, giving the mixture a foamy base that holds its shape while baking.
- Cocoa powder
- Supplies chocolate flavour and colour, and adds dryness that helps the kisses firm up.
The step that matters
Baking until dry. A slow oven dries the sugar and egg-white structure without browning them. Pulling the kisses too early leaves them sticky and soft in the centre.
