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):

  1. Sweet potatofits better
  2. Capsicumfits better
  3. Arrowrootfits about as well
  4. 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.
