I decided at practically the last minute to join the Food in Jars Mastery Challenge, and this is my actual last minute entry for January. This month’s preserve is marmalade. I’ve made marmalade once before. A coworker brought a huge bucket of backyard Meyer lemons into the office and let me take 3 pounds for free. I made 5 half pints, I think, and I ended up giving all of them away as gifts. Time to try it again and actually keep some this time!
