Inspired by a post a friend wrote on Facebook ages ago, I made lemon curd in order to use up a couple of left over lemons. I'd never made it before, but it was very successful. I think I will be making it again.
@Cantras It ended up very much like the best shop bought lemon curd, though I may try a bit less sugar next time. I used a recipe from Mrs Beeton for quantities. Friend's recipe off the internet had 90g of sugar for 2 lemons rather than the 225g I used. Possibly try somewhere in between?
