Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
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
Mix the milk with the ground rice.
Gradually add the chocolate, stirring until smooth.
Heat the mixture over medium heat until it thickens, then let it cool slightly.
Stir in the beaten eggs.
Make the crust
Combine the wheatmeal and butter with a little cold water to form a paste.
Line a greased pie plate with the paste.
Bake the tart
Pour the cooled custard into the lined plate.
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.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
