Sorry hit send before I meant to... You can find all the recipes for preserved lemons online. I love the recipe from A Boat A Whale and A Walrus.

For pasta it does great as a an add-on when you add in garlic. For salad just minced and added (or in the vinaigrette). When you toast it, it takes high heat amazing. Great with chicken or Brussels.
Anyways, I'm happy your interested. Have fun!
