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 ↓
Rice Cake
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.
Prepare
Preheat the oven to 350°F (175°C).
Weigh the eggs in their shells and use the same weight for sugar and butter.
Make and bake the batter
Mix the rice flour and all-purpose flour together.
Beat the eggs and sugar until well combined.
Add the flour mixture and stir in the butter until smooth.
Pour the batter into a greased cake pan.
Add any desired flavoring before baking.
Bake for about 1 hour and 10 minutes or until a toothpick comes out clean.

Butter and flour 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
- Eggs
- Provide structure and moisture, and trap air when beaten to help the cake rise.
- Sugar
- Adds sweetness and helps keep the crumb tender and moist.
- Butter
- Adds fat for richness, moisture and a tender texture.
- Rice flour
- Gives a light, tender crumb because it forms little gluten.
- All-purpose flour
- Provides the wheat proteins that form gluten, giving the cake structure.
The step that matters
Stirring in the flour mixture and butter. Stirring only until smooth matters because overmixing wheat flour develops too much gluten, which makes the cake tough and dense.
