Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to give the cake a tender, rich crumb.
- Eggs
- Add structure and richness to the batter and thicken the custard as it sets.
- Flour
- Forms the main structure of the cake batter.
- Baking powder
- Releases gas in the batter so the cake rises and stays light.
- Cornstarch
- Thickens the custard so it holds its shape between the cake layers.
- Hickory nut meats
- Add crunch and a rich, nutty flavour to the custard filling.
The step that matters
Heating the custard milk. Heating the milk gently in a water bath keeps it from scorching on the bottom. Cornstarch needs to be fully dissolved first so it thickens smoothly without lumps once combined with the eggs and sugar.
