Delia has two foolproof (for me anyway) recipes: plain ones which have to be eaten at once, & Mediterranean ones from her 'Winter' cookbook.
I've never had scones which spread - I didn't know anyone could do that!!
The other day I adapted her plain scone recipe to make cheese scones - just leave out the sugar & add some mustard & grated cheese. Brush with the leftover milk/egg mixture & sprinkle grated cheese over. They made a fantastic lunch.
I don't bother rolling out the scone mix - too much faffing around - so I just divide up the mix & roll each piece in my hands then put it on the baking tray & flatten it slightly, keeping it nice & tall. They look a bit rustic but all the better for it, I think.
I once made scones for a baking competition at the local horticultural show & lost points because everyone except me knew that sweet scones need a round cutter while savoury ones use a wiggly cutter. Or vice versa, I can't remember, but I did it the wrong way round.
Rat & Crowd, how can you not make sponges? Especially if you can make fairy cakes. Maybe I'm doing it wrong, but my fairy cake recipe is the same as my sponge recipe: 2oz of everything & 1 egg plus vanilla essence, baking powder & a few grains of salt.
Nigella cured one of my failures. DH used to complain that my crumbles were too stodgy & solid. Then I saw Nigella on TV & she put baking powder in hers - how did I not know/think of that? Anyway, mine are fine now & DH loves them.
