Lemon Custard

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Preheat the oven to 350°F (175°C).

Make the custard

  1. In a bowl, combine the grated lemon, eggs, milk, grated crackers, melted butter, and sugar, and mix well until fully combined.

  2. Pour the mixture into a pastry shell.

Bake

  1. Bake until set and lightly golden.

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 firm, sliceable texture as they cook.
Milk
Provides the liquid base that the eggs thicken as it bakes.
Grated crackers
Add body and help thicken the filling as the custard sets.
Melted butter
Adds richness and fat, giving a smoother, softer texture.
Grated lemon
Supplies the bright, aromatic lemon flavour and its zest oils.

The step that matters

Bake until set and lightly golden. Egg proteins coagulate as they heat, so underbaking leaves the custard runny while overbaking makes it grainy, weepy and rubbery. Look for a set centre that wobbles slightly.

Swap the lemon

How well each one fits the dish's main ingredients (egg, milk, butter, sugar):

  4. Lemonthe original

Fit is the average pairing score against egg, milk, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
