I saw your purple broccoli post and thought of this.
The lemons are super easy to make. Many say they should be meyer lemons, but that is bunk, although they do have thinner skins. Just get some lemons, a lot of good salt, I put some peppercorns, coriander seeds and cumin seeds in too. cut the lemons in quarters but leave them attached at one end, then pack them in the salt mix so the flesh is spread out and it's all covered nicely. Two weeks or more. I use the salt for cooking - nice mild flavor. so easy, so good.
They are delicious raw too if you ask me, so that salad sounds both yummy and beautiful!
