How to make Sour cream and onion biscuits

  1. Place a rack in the middle of the oven and preheat to 220°C (fan) or 230°C (conventional).

  2. In a large bowl, whisk together the salt, pepper, baking powder, baking soda, sugar, and 315 g of flour until well combined.

  3. Add the chilled butter and toss to coat the pieces in flour.

  4. Using your hands, work the butter into the dry ingredients until the mixture resembles flat pieces with some pea-sized bits remaining.

  5. Add the chopped scallions and toss to distribute them evenly throughout the mixture.

  6. Create a well in the centre of the mixture and pour in 300 ml of sour cream.

  7. Using a fork, mix in a circular motion until large shaggy clumps form.

  8. Turn the dough out onto a lightly floured surface and knead it once or twice until it comes together, flouring your hands if necessary.

  9. If there are any loose bits, gather them into the centre of the dough and knead once more to incorporate.

  10. Pat the dough into a rectangle measuring approximately 20 x 10 cm and about 2.5 cm thick.

  11. Starting from one short side, fold the dough into thirds as you would a letter; it doesn't need to overlap perfectly.

  12. Pat the dough into another rectangle measuring 20 x 10 cm, then fold it in thirds like a letter again.

  13. Pat the dough back into a rectangle measuring 20 x 10 cm and cut it in half lengthwise.

  14. Cut each half crosswise into 4 squares, resulting in a total of 8 biscuits.

  15. Transfer the biscuits to a baking tray lined with parchment paper.

  16. Brush the tops gently with melted butter and sprinkle with sea salt.

  17. Bake the biscuits until golden brown, about 18–22 minutes.

  18. Serve warm with sour cream or additional butter for slathering.
