Last year I had promised to post a reminder when it was time to make lemon and lime pickle in the sun (in the US). The sun is out, the days are long and the time is right.
If you can get hold of organic limes and lemons, more power to you! I looked high and low (ok! just in Sunnyvale Farmers' Market) for Meyer lemons but found none. I saw organic Eureka lemons and I am kicking myself for not bringing some home with me. I had to settle for Citrons and Persian limes. Don't forget to wash them well to get rid of the coating made of bees-wax.
Time to go solar!
