So I dont understand why you cant just tightly close a tin lid. isnt it the same as tightl closing a mason jar lid? still air in each of them. My tin has dried out, you guys just tossing the stuff in a jar and closing it by hand calling it good? or actually boiling it like canning. never did that before. Is a small ziplock bag good enough? I got a sampler off or tmoran and still have a few ziplocks left to get through, is that good enough or buy some small jars and toss them in? Guessing ill have to wet a paper towel and toss it in a jar with my half tin of midnight ride to rehydrate it.
