Grew up with preserved lemon peel as one of many choices at the crackseed store. This is how we would do it, others had different ways. Get sterilized glass jar and lid. Hot water would get the wax off if there was any, just rinse well if no wax. Pack in jar with layers of salt, layers of lemons. Roll/flip every couple days for week then let sit about 6 weeks. Use the rind for sucking on when throat is sore. Or chop up on chicken or fish. Made a chimichurri like thing as well. Save the leftover salt as well for use. shrug

I knew my eggs was headed for dat big omelette in da sky!
