150g bacon
125g fleur de sel (flaky sea salt)
In a frying pan, gradually brown the bacon without adding any fat. Take it out, drain it on absorbent paper and let it cool. Pass the bacon through a food processor or spice grinder in one or more batches, then take it out.
Mix the salt with the bacon, run it through the food processor or spice grinder again, then put it in the jars and close well.
Keep in a cool, dry place away from the sun.
