One thing I learned was, if you buy tomatoes "on the vine" they last longer. Leaving what I think of as "the collar" on the tomato is apparently key. They did a study where they took tomatoes picked at the same time, and studies various options - apparently the leaves staying intact keep oxygen from permeating and aging the tomato faster!
What is your favorite summer fruit or veggie tip?
I do not have garden where we are now, it has been many years since I could grow vegetables safe for consumption, but I still look forward to local cucumbers, squash, etc. hitting the markets!
Scored and sliced cucumbers in vinegar and salt? Yum!
