I often make half quantities - as I know I'm going to eat them all. (I mean to freeze some, but it rarely happens.)
Vegan scones:
400g self raising flour
half teaspoon bicarbonate of soda
100g vegetable margarine (I use Flora - as you need a high fat content)
200ml water - or oat milk
bake at 200C for about 12 minutes
Scones get tough if they are kneaded or overworked. I just make a round, about an inch thick, and cut almost through into slices.
You could add some raisins or sultanas (soaked then drained) - or a little strong, grated cheese and some mustard powder.
