Preheat oven to 180°C/160°C fan/gas 4 then line a 12 cup muffin pan with paper cases.
Use electric beaters to beat the butter, sugar and lemon zest in a bowl until pale and
creamy. Add eggs, one at a time, beating well after each addition. Add the flours and milk
until combined. Divide mixture into paper cases. Bake for 20 minutes.
Once cooked, cut a deep hole from the centre of each cupcake
and spoon 1 tablespoon of
lemon curd into the hole.
For the meringues, whisk the egg whites until soft peaks form. Continue whisking and
gradually add sugar 1 tablespoon at a time. Continue whisking until all sugar dissolves.
Use a piping bag to pipe the meringue mixture over each cupcake. Use a cook’s blowtorch to
lightly toast the meringues or bake again for 5 minutes until toasted.
