Pumpkin for Five

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.

Make the custard

In a large bowl, combine the pumpkin, milk, sugar, eggs, flour, molasses, and cinnamon.
Mix until smooth and well combined.

Bake

Pour the mixture into a greased baking dish.
Bake in a preheated oven at 350°F (175°C) until set.

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

What each ingredient does

Eggs: Set the custard as they cook, giving it structure and a firm texture.
Pumpkin: Provides the main body, moisture and pumpkin flavor of the custard.
Milk: Adds liquid and richness, helping the custard become smooth and tender.
Flour: Thickens the mixture and gives the custard more body as it bakes.
Sugar: Adds sweetness and helps balance the flavor of the pumpkin and spices.

The step that matters

Bake until set. Pull the custard once it is just set. Eggs firm up as they heat, so overbaking can make the custard grainy, cracked or rubbery.
