Yeah, googling told me they were easy to make but you have to let them sit for quite a while, so not so great if you just want to try out a recipe. I actually did try the lemon preservation myself, because after failing to find them I was curious enough. And some months later I tried the stew recipe. Though I wasn't entirely sure whether my lemons had turned out the way they were supposed to be. Either way the stew didn't impress me and then I had the rest of those lemons sitting in my kitchen for a while without any idea what else I might use them for.
