Advice:

Use Clean Lemons: Ensure that the lemons you use are clean and free from any visible damage or blemishes. Washing them thoroughly before slicing will help remove any dirt or contaminants.

Choose Quality Salt: Opt for high-quality salt, such as sea salt or kosher salt, for the pickling solution. This can enhance the preservation process and contribute to the flavor of the lemons.

Sterilize Containers: Before placing the lemon slices in the container, make sure it is clean and sterilized. This helps prevent the growth of unwanted bacteria and ensures a hygienic preservation environment.

Experiment with Additional Flavors: Consider adding herbs or spices to the saltwater mixture for added flavor. Some options include peppercorns, bay leaves, or coriander seeds. This can impart a unique taste to the preserved lemons.

Adjust Salt Concentration: You can experiment with the concentration of salt in the water to find the taste that suits your preference. However, be cautious not to use too much salt, as it may overpower the natural flavor of the lemons.
