How to make Preserved Lemons

Whole lemons cured in salt and their own juice until the rinds turn soft, tender, and intensely citrusy. Expect about 20 minutes of active prep, then 3-4 weeks of curing, with the softening rind as the main sign it is ready.

Quick answer

Cut and salt the lemons, then pack them tightly into a clean jar and cover them with salt and juice. After 3 days, make sure the salt has drawn out enough juice to cover the lemons, and top up if needed. After 21 days, check whether the rinds have softened and taste a sliver to judge the cure. After 28 days, confirm the rinds are soft, then move the jar to the fridge to keep.

Safety

  • • Use plenty of salt. The heavy salt and the acidic lemon juice together are what preserve the lemons.
  • • Keep the lemons submerged in their salty juice and top up with more lemon juice, never water.
  • • Always use a clean fork to remove lemons so you do not introduce mold.
  • • A clean salty-citrus smell is normal. A rotten smell or fuzzy mold means the batch should be discarded.

Step-by-step

Day 0

Step 1: Prepare and pack

Cut and salt the lemons, then pack them tightly into a clean jar and cover them with salt and juice.

  • Set up clean equipment Wash the jar and any utensils before you start.
  • Prepare lemons Scrub the lemons, then cut each one into quarters that stay joined at the base.
  • Salt the lemons Pack salt generously into the cuts of each lemon.
  • Pack and submerge Press the lemons into the jar, then top up with salt and lemon juice until they are covered.
Day 3

Step 2: Check and top up

Make sure the salt has drawn out enough juice to cover the lemons, and top up if needed.

  • Check submersion Press the lemons down and check that the juice has risen to cover them.
  • Top up juice Add fresh lemon juice if the lemons are still poking above the liquid.
  • Check aroma The jar should smell fresh, salty, and citrusy rather than rotten.
Day 21

Step 3: Check readiness

Check whether the rinds have softened and taste a sliver to judge the cure.

  • Check rind softness Press a lemon against the side of the jar to feel whether the rind has gone soft.
  • Taste a sliver Rinse a small piece of rind and taste it to judge the balance of salt and citrus.
  • Resubmerge and cover Press the lemons back below the juice before returning the jar to its curing spot.
Day 28

Step 4: Finish and store

Confirm the rinds are soft, then move the jar to the fridge to keep.

  • Taste final batch Confirm the rinds are soft and mellow enough to use before moving the jar to cold storage.
  • Refrigerate lemons Keep the lemons submerged in their juice and refrigerate the jar to slow the cure.

What to look for

  • • Day 0: The lemons are packed tightly, coated in salt, and pressed down under as much juice as they give so far. The salt will keep drawing out juice over the next few days until they are covered.
  • • Day 3-4: The salt has drawn out enough juice to cover the lemons and the rinds are just starting to soften. Top up with fresh lemon juice if any lemons are still poking above the surface.
  • • Day 21 and beyond: The rinds feel soft, the juice looks syrupy, and a rinsed sliver tastes mellow and intensely lemony. Soft rind is the sign the lemons are ready, usually after 3-4 weeks.

Troubleshooting

  • The lemons are not covered by juice after a few days. The lemons were not pressed down enough or did not release much juice. Press them down firmly and top up with fresh lemon juice until they sit below the surface.
  • A thin white film forms on the surface. Surface yeast, which is common on salty cures and usually harmless. Skim it off, make sure the lemons stay submerged, and keep going if the smell is still clean.
  • The rinds are still firm after four weeks. The kitchen is cool, so the cure is running slowly. Leave the jar to cure for another week or two and check the rind softness again.
  • The lemons taste extremely salty. That is normal for preserved lemons, which are used as a strong seasoning. Rinse each piece before using it and use small amounts to season dishes.

Storage

Once the rinds are soft, keep the lemons submerged in their juice, seal the jar, and refrigerate. To use, lift out a piece with a clean fork, rinse it, scrape away and discard the salty pulp, and finely chop the rind.

Shelf life: about 6-12 months refrigerated

Serving suggestions

  • • Chop the rind into tagines, stews, and braises.
  • • Stir it through grain salads, dressings, and yoghurt sauces.
  • • Add slivers to roasted vegetables, chicken, or fish.
