Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, giving the cake a tender crumb.
- Egg white
- Helps bind the batter and gives the cake structure as it sets.
- Hazelnuts
- Provide the main body and nutty flavour of the cake.
- Flour
- Gives the batter structure so the cake holds its shape while baking.
- Chocolate
- Forms the rich, glossy topping and adds bittersweet flavour.
