The recipe is from The Good Housekeeping Cookery Book which I have to say is going to be one of the most important cooking books I own. It has everything you would need it in from cut of meet, to preserves, to how to make different kinds of pastry. I love it but have been a bit daunted by its size and haven't delved into the pages before today.
This really couldn't have been much more simple to make and I am so excited about having homemade lemon curd in the fridge. It's just as simple as jam and really scrummy and fresh.
