Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard into a sliceable structure as their proteins coagulate with heat.
- Potato starch
- Thickens the batter and gives the baked custard a smooth, tender texture.
- Milk
- Provides the liquid that turns the mixture into a pourable batter and adds moisture.
- Sugar
- Adds sweetness and helps keep the custard tender.
- Cinnamon
- Adds warm aroma and flavor to the custard.
The step that matters
Baking in a water bath. The mold sits in hot water so heat reaches the custard gently and evenly. Strong direct heat can overcook the eggs, causing the custard to curdle, weep, or turn rubbery.
Swap the potato
How well each one fits the dish's main ingredients (cinnamon, egg, sugar, milk):
- Sweet potatofits better
- Capsicumfits better
- Arrowrootfits about as well
- Potatothe original
Fit is the average pairing score against cinnamon, egg, sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
