Banana Custard

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare the custard

  1. Mash the bananas to a pulp.

  2. Add the beaten eggs, castor sugar, and vanilla to the bananas; stir well.

  3. Mix in the milk until combined.

Bake or steam

  1. Pour the mixture into a baking dish or a steaming basin.

  2. If baking, dot the top with tiny pieces of butter; if steaming, butter the basin.

  3. Bake at 400°F (200°C) or steam until set.

  4. Serve with a rich custard if steamed.

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

What each ingredient does

Bananas
Provide the main flavour and body, softening into the custard as it cooks.
Eggs
Set the custard as they cook, giving it structure and a tender texture.
Milk
Supplies liquid that the eggs set into a soft, creamy custard.
Castor sugar
Adds sweetness and balances the flavour of the bananas.

The step that matters

Bake or steam until set. Eggs set through gentle heat, and overcooking at high temperature can make the custard curdle, weep liquid, or turn rubbery. Check for a set centre rather than relying only on time.

Swap the banana

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

  1. Figfits about as well
  2. Peachfits about as well
  3. Coconutfits about as well
  4. Bananathe original

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