Homemade Curry Powder Recipe

One of the types of food I make most often in my house is curry- an Indian dish made with a variety of different spices, giving it an "Indian flavor" and each curry has its own unique spice mix, and there are even specific curry spice mixes known as garam masala or panch phoron.
But sometimes you want just a simple curry powder, the equivalent of what they sell in the store labeled as "curry powder", and this is that.
Feel free to use it as is in red lentil dal, with veggies, on meat or fish, etc... or just in any recipe that calls for curry powder.
I left out the hot pepper flakes in it, since I like being able to adjust the heat on my own, but feel free to add some to your mix if you want to.

Homemade Curry Powder Recipe

Ingredients:
2 tablespoons ground cumin
2 tablespoons coriander seeds
2 teaspoons ground turmeric
1/2 teaspoon mustard seed
1/2 teaspoon ground ginger

Instructions:
1. Put all the ingredients into a coffee grinder and grind until fine, or use a mortar and pestle.

2. If you don't have a coffee grinder or mortar and pestle, you can make this recipe with ground coriander and ground mustard seeds, but use less than the stated amount, perhaps 1 1/2 tablespoons coriander seeds and a 3/8 teaspoon ground mustard seeds.

Enjoy!
