I've got a big patch of sage in the garden, and with the cold coming on, I'd like to preserve some of it. I know that it will keep under the snow for a while (I've trecked out to the patch in early winter to pick off some leaves for a butter-sage sauce). I'm thinking freezing the leaves directly, but I'd like to hear if anybody has tried other techniques or has interesting tricks.
I also have a big bushy tarragon, from which I make a yearly batch of tarragon vinegar. Sage vinegar might be overwhelming though. Maybe a small batch... Mmmmh.
