Peel and slice the turmeric into thin rounds. Chop the chilies into bite sized chunks.
Add to a bowl. Top with lots of lime juice and salt. Mix well.
Transfer the contents to a glass jar and refrigerate.
Notes
I love these little rounds, but if you want, you can also julienne the turmeric. This can be a bit tough to do, since turmeric root is quite tough, but this version can soak up the flavors more quickly. I did the same with my pickled shredded carrots and I found that the thin juliennes absorb the flavors more rapidly.
Another great idea is to chop the turmeric into small cubes.
Make sure you peel the turmeric well and wash and pat dry them before you use them for the recipe. This will help keep them from spoiling quickly.
Pickled turmeric tastes best when consumed 2-3 days after you make it. Raw turmeric can have an intense taste and flavor, which mellows down with time. I would recommend making this a few days ahead of time, and then enjoying it.
If you don't have enough lime juice to keep all the turmeric and green chilies covered, use a spoon to move the turmeric around or just shake the jar occasionally. This will help prevent spoilage.
