Edit: Sauerkraut. I forgot to mention the sauerkraut.
I took the past four Friday afternoons off in order to do some food preservation. The summer weekends always seem so busy and there's no time during the week for more intensive tasks.
This month, I canned two types of jam and pickled hot cherry peppers; made and froze a couple of loaves of zucchini bread; froze some corn and beans; and made refrigerator pickles.
There are still some things I need to can or freeze, but with September around the corner, I should have more time on my hands.
If I had to do it again I would just take off two full Fridays at the end of the month, which is probably what I'll do next year.
