Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Cream the butter and sugar together.
Add the mace or nutmeg, curds, beaten eggs, currants, and biscuit crumbs; mix well.
Line tart tins with flaky pastry.
Place a good spoonful of the mixture in each tin.
Bake
Bake in a 400°F (200°C) oven for about 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Curds
- Provide the main body of the filling, setting into a soft, rich custard-like texture.
- Butter
- Adds richness and tenderness to the filling and carries flavour.
- Eggs
- Bind the filling and help it set firm as it bakes.
- Castor sugar
- Sweetens the filling and helps the creamed butter become light.
- Currants
- Add chewy pockets of sweetness and fruit flavour throughout the filling.
The step that matters
Placing the mixture in the pastry. A good spoonful in each tin should fill the pastry without overflowing. Too much filling can spill over and burn, while too little leaves the tart thin. Even portions help the tarts bake at the same rate.
Swap the mace
How well each one fits the dish's main ingredients (sugar, butter, currant, egg, biscuit, lemon):
- Cinnamonfits better
- Nutmegfits better
- Capersfits better
- Macethe original
Fit is the average pairing score against sugar, butter, currant, egg, biscuit, lemon. Candidates are from the same food group and used in at least 100 recipes.
