Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Sweet potatoes: Provide the bulk and starch that gives the cakes their body and tender interior.
Egg yolks: Bind the grated sweet potato together and add richness to the cakes.
All purpose flour: Absorbs moisture and helps the cakes hold their shape while cooking.
Dark brown sugar: Adds sweetness and promotes browning at the cake edges through caramelization.
Butter: Conducts heat in the skillet and adds fat for golden browning and flavor.

The step that matters

Cook gently until browned around the edges. Grated sweet potato and sugar brown quickly, so high heat can scorch the outside before the centre cooks through. Gentle heat lets the starch set and the sugars caramelize evenly.
