Ever notice how a plastic bag gets cloudy looking? That's trichs off the bud. Glass is best.
I won't argue with you that glass is a great solution, but turkey bags don't really get that cloudy look. They are a totally different material, meant to withstand oven temperatures for many hours while baking a roast or a bird.
And you save on labour, time, money, and space. Plus it's much easier to turn the buds in a big bag.
