I made scones for the first time last week using 3 cups SR flour and a cup each of cream and lemonade, placed them nice and close together and brushed with milk. They tasted nice but weren't very high.

I popped them into a preheated oven of 220C, then turned it down to 180C for just under 20 minutes. Should I have had the oven hotter? What about adding some baking powder to raise them a bit more? If so, how much?

Any hints?

TIA.
