Olive Cake

Another recipe I don't want to lose! This one came from my sister's sister-in-law in France, and it's divine...

100 grams flour (add a little more if the mixture is too wet)
150 grams grated cheese (preferably gruyere)
4 eggs
4 tablespoons olive oil
1 small glass of white wine
2 teaspoons baking powder
200 grams pitted green olives, sliced (nice with pimento stuffed olives)

Mix all together and bake in a greased 22 inch ring tin (or any suitable pan) for about 40 mins at 200 C.
