I had a good search around and combined several recipes and it seemed to work OK.
simple ingredients: self raising flour, butter, milk, egg and then cheese and spring onion. Added flavourings such as mustard powder or paprika, but try without if you don't have any
This is what I used
225 gms Self Raising flour
- rub these together so that they resemble fine breadcrumbs, then add 6 finely chopped spring onions and half a teaspoonful of mustard powder (or try paprika, or just salt and pepper if you don't have any of that)
Then add 75gms of grated cheese
Mix together then add
1 beaten egg and top up this with milk to make up 125mls in total, save a tiny drop and brush this on the top of the scones before baking.
Lightly knead together.
Make into a 2.5 cms thick, I just gently flattened with hand.
Then use a round cutter to make 6 scones, or just cut this into 6 triangles, brush the tops with the reserved egg/milk mix
and bake for 12 minutes at 200c/400f/gas mark 7
or you could make into a round and mark it into 6 - and bake for slightly longer.
