Chocolate Tarts

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

  1. Mix the milk with the ground rice.

  2. Gradually add the chocolate, stirring until smooth.

  3. Heat the mixture over medium heat until it thickens, then let it cool slightly.

  4. Stir in the beaten eggs.

Make the crust

  1. Combine the wheatmeal and butter with a little cold water to form a paste.

  2. Line a greased pie plate with the paste.

Bake the tart

  1. Pour the cooled custard into the lined plate.

  2. Bake the tart for 30 minutes in a moderate oven at 350°F (175°C).

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

What each ingredient does

Eggs
Beaten eggs set the custard when heated, giving it body and structure.
Milk
Forms the liquid base of the custard and thickens with the ground rice and heat.
Ground rice
Starch that thickens the milk and gives the custard a smooth, sliceable texture.
Allinson chocolate
Provides the main flavour and, as it melts, adds richness to the custard.
Allinson fine wheatmeal
Forms the flour base of the paste that holds the tart shell together.
Butter
Adds fat to the pastry paste, contributing tenderness and flavour.

The step that matters

Cooling the custard before pouring. Heating the custard until it thickens and then letting it cool slightly keeps the hot liquid from thinning the pastry and lets the eggs set evenly in the oven rather than curdling or leaking.
