Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Chocolate Macaroons
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the paste
Melt the chocolate in a pan over low heat.
Mix the melted chocolate with powdered sugar and egg whites to form a thick paste.
Roll the mixture to about ¼ inch thick.
Cut into small round pieces using a cutter.
Bake and serve
Butter a pan and dust it with equal parts flour and sugar.
Place the cut pieces on the prepared pan.
Bake in a hot oven at 400°F (200°C) until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Provide structure and lightness, helping the paste hold its shape and set in the oven.
- Powdered sugar
- Adds sweetness and bulk, giving the paste body so it can be rolled and cut.
- Plain chocolate
- Adds rich flavour and fat, and helps firm the paste as it cools and sets.
The step that matters
Rolling and cutting the paste. The paste is thick and sticky, so rolling it to an even thickness keeps the pieces uniform and lets them bake evenly. Uneven pieces will set at different rates and can dry out or brown unevenly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
