Cook potatoes in their skins until soft. Drain and mash.

Preheat oven to 400F/200C.

Mix flour, baking powder and salt in a bowl. Cut up butter into small pies and mix into flour with hands until you get a sandy/crumbly texture.

Mix in caraway/dill seeds and cheese here if using.

Add mashed potatoes and work into the dough. Add a tablespoon of milk if needed to help make dough formable (might not need milk if using leftover mashed potatoes that are creamy).

Roll out in into a plump cylinder and cut dough into 4 equal pieces. Form each into scones, place on a greased baking sheet (or on wax paper). Bake for about 15 minutes or until golden brown.
