Jersey Milk and Jersey Royal Potato Waffles with Black Butter Caramel

**Waffle Batter:** In a large bowl, whisk together the flour, baking powder, and sugar.

In a separate bowl, whisk together the mashed Jersey Royal potatoes, egg, Jersey milk, melted Jersey butter, and vanilla extract (if using).

Pour the wet ingredients into the dry ingredients and gently mix until just combined. Do not overmix.

Preheat your waffle iron according to the manufacturer's instructions. Grease the waffle iron with melted Jersey butter.

Pour the appropriate amount of batter onto the hot waffle iron and cook until golden brown and crispy, according to the waffle iron's instructions.

**Black Butter Caramel:** While the waffles are cooking, prepare the Black Butter caramel. In a medium saucepan, melt the Jersey butter over medium heat. Continue cooking, swirling occasionally, until the butter turns a dark brown and emits a nutty aroma (this takes a few minutes, watch it carefully to avoid burning).

Add the sugar, cider vinegar and black treacle to the browned butter. Stir until the sugar dissolves.

Add the chopped apple and lemon juice to the pan. Stir occasionally and simmer for 5 minutes until the apple is soft and the sauce has slightly thickened.

Serve the waffles immediately, topped with the warm Black Butter caramel and fresh Jersey blackberries (if using).
