The cayenne pepper was a really good addition and added a little spiciness to the dish.
I served it with a large side salad.
3 medium potatoes, sliced
1 onion, sliced
2 cloves garlic, finely chopped
284ml/small pot double cream
handful cheddar cheese, grated
pinch cayenne pepper
Preheat the oven to 200C. Layer the onion and potatoes in an oven proof dish, sprinkle over the garlic. Pour the cream over the dish, sprinkle over the cayenne pepper and bake for about 20 mins or so.
Then take it out of the oven and sprinkle over the grated cheese, put back into the oven and bake for another 10-15mins or until golden and bubbling.
