One of my favorite ways to use herbs is to make a good herb vinegar. You can use all kinds of herbs and here is how you make it...
Heat Vinegar until hot but not boiling (I use cider)
Pour over your favorite herbs. ( such as basil, rosemary, thyme, chives, dill, sage etc..) mix and match to find the herbs you like best together.
Pour this into a glass jar and let it set for about 2 weeks. strain herbs before you use.
