Ingredients
Method
- Heat the oven to 425°F (220°C). Melt 35 g butter in a deep skillet. Cook the onion, carrot and celery over medium heat for 7–8 minutes, stirring, until the onion is translucent. Stir in 35 g flour for 1 minute. Gradually whisk in the stock and milk; simmer for 4–5 minutes until the sauce coats a spoon. Stir in turkey, peas, thyme, 2 g salt and pepper, bring back to a gentle simmer, then transfer to a 9-by-13-inch (23-by-33-cm) baking dish.

- Whisk 220 g flour, baking powder and 3 g salt. Rub in 55 g cold diced butter until pea-size pieces remain. Stir in the cheddar, then gently fold in the cold buttermilk just until no dry flour remains. Drop eight roughly equal mounds over the hot filling, leaving gaps between them.

- Bake for 22–26 minutes, until the biscuits are golden, a skewer inserted in a biscuit comes out without raw dough, and the filling reaches 165°F (74°C) in the center and several places. Tent loosely with foil if the tops darken early. Rest for 10 minutes before serving.
