1 Preheat the oven to 180ºC/Gas Mark 4.

2 Line a muffin tray with 6 silicone moulds. If you don’t have silicone moulds you can grease your muffin tray with some oil, but the cupcakes will be more difficult to get out.

3 Add the milk and pepper to your whisked eggs, whisk again and set aside.

4 Place a tablespoon of grated sweet potato into each silicone mould. Crumble the feta cheese on top of the sweet potato.

5 Pour the egg mix into the silicone moulds and fill to the top. Bake in the oven for 15-20 minutes, until golden and cooked through then set aside to cool.
