Do I need to ferment preserved lemons?
Not in the kombucha-science sense. This is primarily a salt cure that creates a very unfriendly environment for bad microbes while softening the peel. Some natural fermentation can happen, which is totally normal, but you are mainly aiming for tender peel and salty lemony brine.
How long until preserved lemons are ready?
Usually 3 to 4 weeks at cool room temperature. If your kitchen is cold, it can take closer to 5 weeks. They are ready when the peel is soft and you can easily cut through a quarter with a spoon.
Do I have to use organic lemons?
I strongly prefer organic here because you eat the peel. If you cannot, scrub the lemons very well with hot water and a brush, then dry thoroughly.
What salt should I use?
Kosher salt is the easiest and most reliable. Avoid iodized salt if you can because it can taste a little harsh. Fine sea salt works, but measure by weight if possible since it packs more densely than kosher.
Do I rinse preserved lemons before using?
Most of the time, yes. Rinse the piece you are using under cool water, then use mostly the peel. You can keep a bit of the pulp if you want extra punch, but it is salty. Taste as you go.
What part do I cook with?
The best part is the peel. For many dishes, scrape out the pulpy interior (it can be very salty and a little bitter), then finely chop the peel.
Can I add spices?
Absolutely. Bay leaf, peppercorns, coriander seed, cinnamon stick, and a pinch of chile flakes all play nicely. Just keep it simple so lemon stays the star.
