4 Meyer lemons, scrubbed and dried well
3/4 cup kosher salt
1 1/2 cups fresh lemon juice from 8 lemons
Cut each lemon lengthwise into quarters, stopping 1 inch from bottom, so lemons stay intact at base.
Hold 1 lemon over a bowl and pour 1-3 tablespoons of salt into cavity of lemon, depending on the size of the lemon. Gently squeeze lemon, rubbing cut surfaces together. Place lemon in 1-quart glass Mason jar. Repeat with remaining lemons and salt. Add accumulated salt from bowl to jar.
Pour lemon juice into jar so lemons are submerged. Cover jar tightly with lid, shake, and refrigerate, shaking jar once per day to redistribute salt and juice for first 4 days. Let lemons cure in refrigerator until glossy and softened, 4 to 6 weeks.
When ready to use, cut off desired amount of preserved lemon. Using knife, remove pulp and white pith from rind. Slice, chop, or mince rind as desired. (For uncooked applications, rinse lemons to remove excess salt before using.)
