What spices are in this curry?
- Yellow curry powder is a spice blend made up of many different ground spices. The mix usually includes at least ginger, cumin, cinnamon, coriander, cardamom and turmeric. (Turmeric is mainly what gives the blend its characteristic brilliant yellow-orange color.)
- You can use mild, medium or hot chili powder and yellow curry powder, depending on what spice level you want.

- Turn the heat down, then move the chicken thighs over to one side of the Dutch oven. Add fenugreek, cumin, coriander and mustard seeds to the other side. Fry the seeds for 4 to 5 minutes. (The seeds need to sizzle but be careful not to burn them.)¼ teaspoon whole fenugreek seeds, ¼ teaspoon whole cumin seeds, ¼ teaspoon whole coriander seeds, ¼ teaspoon whole brown or yellow mustard seeds

Recipe notes:
*I recommend to get the spice blends for this recipe from a dedicated spice shop rather than the grocery store. The quality and freshness of spices makes a huge difference in any dish and that is especially true for curries.
**Use the chicken thighs straight out of the package. There is no need to trim off any fat since the fat will render in the slow cooker.
***If you don't remove the star anise before transferring the mix into the slow cooker, the curry will take on a very strong anise flavor.
Storage: Transfer any leftovers into an airtight container and store in the fridge for up to 2 days.
Freezing: Let the curry cool to room temperature, then transfer into a freezer bag, seal and put in the freezer.

Nicole B: I am most eager to try your recipe but one ingredient baffles me - what is yellow curry powder? Thanks
Nicole B. says
Hi Abhay,
Yellow curry powder is a spice blend. The exact ingredients differ slightly from recipe to recipe but the commonly used spices are coriander, turmeric, ginger, fenugreek, cumin, cinnamon, black pepper, yellow mustard seeds and more. You can get a yellow curry powder blend at a spice shop; I like to use this one from The Savory Spice Shop: https://www.savoryspiceshop.com/products/medium-yellow-curry-powder?variant=41271571579067
