Peeling root turmeric and boiling the peel separately allows you to extract additional curcumin and other beneficial compounds from the peel, which might otherwise be discarded. It also reduces the intensity of the turmeric flavor in the main dish.
Turmeric peel contains curcumin, the active compound known for its anti-inflammatory and antioxidant properties. While the concentration of curcumin is higher in the rhizome itself, the peel still contains a significant amount. Boiling the peel separately allows you to create a turmeric-infused water or broth that can be used in various ways. This method maximizes the use of the turmeric root and minimizes waste. Furthermore, some people find the flavor of turmeric peel to be quite strong or bitter. By boiling it separately, you can control the intensity of the turmeric flavor in your main dish, adding the infused water gradually to achieve the desired taste. The resulting liquid can be used in soups, stews, or even as a tea.
When boiling turmeric peels, add a pinch of black pepper. Piperine, a compound found in black pepper, significantly enhances the bioavailability of curcumin, allowing your body to absorb and utilize it more effectively.
