1. Cooking the Sausage

Cook the sausage in a hot skillet until browned and fully cooked. Drain on paper towels and let cool.

2. Preparing the Dough

1. Preheat the oven to 220°C (425°F) and line a baking sheet with parchment paper.
2. Prepare the butter: Grate the frozen butter and keep it chilled until use.
3. Mix the dry ingredients: In a large bowl, combine flour, baking powder, baking soda, and salt.
4. Incorporate the sausage, cheddar, and chives: Gently mix to distribute evenly.
5. Add the grated butter and stir quickly to achieve a crumbly texture.
6. Pour in the buttermilk gradually, mixing just until a soft dough forms (do not over-mix).

3. Shaping and Baking

1. Form a rectangle of about 2 cm (¾ inch) thickness directly on the baking sheet.
2. Cut biscuits into squares without separating them (this helps them rise better).
3. Brush with melted butter.
4. Bake for 15-18 minutes, until golden brown on top.

4. Serving Suggestions

Serve warm, on their own, with butter, or as part of a breakfast sandwich with a fried egg.
