For the compote, put the gooseberries and 100g/3.oz of the sugar in a saucepan with a splash of water and bring to a simmer, stirring to dissolve the sugar. Cook over a medium–low heat until the fruit is soft, then push
through a sieve into a bowl. Add more sugar to taste and leave to cool.
For the syrup, put the sugar and water in a small saucepan over a medium heat and stir to dissolve the sugar. Bring to the boil and simmer for 5 minutes.
Take the pan off the heat and add the flowers, stirring to coat them in syrup. Leave, covered, to infuse and cool for at least half an hour.
For the cake, preheat the oven to 180°C/350°F/gas mark 4. Whisk the eggs and sugar together (this should be done using a stand mixer or electric beaters for best effect) until a little mix trickled over the surface leaves a trail, and
the mixture has at least doubled in volume.
Sift in half the flour and fold in. Sift in the rest of the flour and fold in.
Finally trickle the melted butter into the batter, folding as you go to minimize the loss of volume, and continue
folding until everything is incorporated.
Divide between the two tins and bake for 25–30 minutes until golden, and firm to the touch. Do not open the oven door before 25 minutes have elapsed or the cake will sink.
from the oven and turn over on to a wire rack, but leave the tins over the top of the sponges for 10 minutes, then remove them. Once cool, drizzle each sponge with 4 tbsp elderflower syrup.
For the cream, whisk the cream and syrup together until stiff enough to spread.
Spread the compote and then the cream over one layer of sponge. Place the other sponge carefully on top and dust with icing sugar just before serving.
