I am about two steps away from switching to mason jars for everything. Now seeing that I can use them to transport my salads for lunch & pack them in advance? So sold! This site is amazing and this link shows a perfect map for newbie mason jar converts and old ones. It gives you the rundown on what goes where to prevent your salad master piece from turning into a gooey mess by noon. Hope you find it as useful as I have!
What do you use mason jars for if you do?
