A simple gulten-free lemon cake topped with a crunchy lemon sugar drizzle. Ground almonds and the lemon drizzle keep it moist, so it doesn't suffer with the dryness associated with gluten-free cakes.
Peel off the baking paper and leave to cool completely. Place one of the sponges on a plate or cake stand. Stir the jam to loosen and spoon onto the cake. Spread almost all the way to the edges.
