Ooh, yes, Cupcakes, a Cherry tomato tart is a lovely idea. I can make it and pretend that it's really summery weather... Right, to add to my '...next year...' list, I will add: amend balance between cherry and bigger tomatoes. I still maintain that I can't have enough tomatoes, but maybe I can in fact have enough cherry tomatoes when the weather is wintry. I'm even harvesting from armpits already!
For chillies, I love love love the Nigella chilli jam recipe. I eat tons of the stuff. I use white vinegar though (cheaper), and normal sugar with pectin separately sometimes. That's cheaper too. And more adjustable. Actually I start with that recipe and sort of freestyle, as I now bung in other stuff.
And today's other top tip (ahem) is for cheapest jam jars, use tesco value lemon curd jars @ 22p each. And bung the contents.
Oh, and to clean up boiled ruined pans, I boil up clothes washing powder in the pot, and that'll take whatever I've ruined back to normal. But if it's sugary, I usually give it a good long soak in cold water first.
