A quicker way to salt cure lemons. I use olive oil, because I use these for savory dishes. If you'd like to use yours in a dish where the flavor of olive oil will be out of place, feel free to use vegetable oil instead. Measurements are not critical. Use as many lemons as it takes to fill your jar, and as much salt and oil as it takes to cover your lemons. Feel free to add paprika, peppercorns, or other spices between the layers of lemons.
