Cut the tops and stalks off of your gooseberries, and give them a good wash.
Butter your pie dish or baking tin, and then lightly sprinkle it with a little bit of icing sugar, before placing your gooseberries in the dish or tin.
In a separate bowl, beat your eggs and sugar together until creamy. Then add your flour, vanilla extract and milk and mix well until combined.
Melt your butter in a small pan and add to the batter, stirring well.
Pour the batter over the gooseberries, and place your dish or tin in the oven for around 35 minutes, or until your clafoutis is puffed and golden brown and a skewer or knife comes out clean. I had to place some baking parchment over my clafoutis at around the 20 minute mark to stop it burning, so keep an eye out!
