This is useful. It goes insanely well with goulash but would work with anything you’ve got that has gravy to soak up. Or, heck, just as an alternative to bubble-and-squeak.
Mash 200g potato nice and dry, then beat in 1 egg, 50ml olive oil and 100ml warm milk. Put 120g plain flour in a bowl with half tsp salt and 1 tsp bicarb of soda. Dump the potato goop in with the flour and mix it all together.
Now get a small cast iron pan hot on a medium-low heat. Get some butter and/or oil hot in the pan and then tip the mixture in, settle it down. Cook on a low heat for 4-5 mins, then free the edges and shift it out onto a plate so you can turn the pan upside-down, put it on top, and tip the thing over to cook the other side. About 4 mins on this side.
Then it goes in a 200C oven for about 7-8 minutes. You should get some bubbles and rise from the bicarb so you end up with a soft and fluffy scone.
