5 Cover and leave in a cool, dark place for a few days.
6 The fruit will have softened down and allow you to pack them tighter. Squeeze in fresh juice of whichever citrus you are using, enough too fill the jar and cover the contents. Cover and seal well. Put back in a cool dark place and leave a few weeks before using. Once you open the jar, store it in the fridge.
7 To use, rinse the citrus in cold water, remove the flesh, scrape of excess pith. Use slivers of the preserved skin to flavour braises, cous cous, rice dishes and roast chicken and tagines.
Herby salt
Use woody herbs to flavour salt, such as rosemary, thyme, bay leaf and even lemon verbena might work, or citrus zest.
1 Pack plain salt into jars, layering the herb sprigs amongst it.
You can use a finer salt for this as this seasoned salt is nice to offer on the table as well as using in your cooking.
