Ginger root, as much as you want
1. Wash and peel the ginger root, and cut into 1/2 inch slices.
2. Place the ginger into your Vitamix (or another very strong) blender. Start on low setting, increase speed from 0 to 5, use the tamper if large chunks of ginger get stuck. When the mixture is more or less uniform, increase the speed to 10, then set it to High and let process for another 15 seconds.
3. Line a small shallow freezer-safe dish (I use a plastic cover of a Pyrex) with parchment paper, and scoop out the ground ginger onto the dish. Flatten the ginger puree with a spatula, and freeze for about 2 hours.
4. Remove the ginger from the freezer, flip the ginger onto a cutting board, peel off the paper, and cut the ginger into squares. Place the squares into a freezer bag and freezer until required.
I love this method and use it with lots of herbs and spices: lemongrass, roasted garlic, parsley, basil, you name it. It is particularly great for highly perishable herbs. For ginger, it saves you a lot of time: you do all the peeling, the grinding and the washing once every couple of months, and have freshly ground ginger whenever you need it in a second.
