Wash the basil, shake dry, pluck the leaves and cut into strips. Cut the chorizo into pieces. Crumble feta coarsely. Melt fat
Mix flour and baking powder in a bowl. Whisk eggs, crème fraiche and milk. Add egg mix, pesto and fat to the flour and mix everything to a smooth dough. Finally fold in chorizo, basil and cheese, season with salt and pepper
Grease a box form (approx. 11 x 30 cm) and dust with flour. Pour the dough into the tin and bake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) for approx. 40 minutes (test with sticks)
Take the cake out of the oven and let it cool down for about 10 minutes. Turn the cake out of the tin and let it cool down on a cake rack
