Kadugu also spelled as Kaduku is the Malayalam word for Mustard seeds usually the Black Mustard Seeds which is one of the important spices in Kerala Cuisine. Kadugu is always present in almost all dishes prepared in Kerala, India. 

My family friends in Allepey, a district in Allepey always used Kadugu when cooking their dishes, like Sambar, Thoran , and stir-fry dishes which you will see in many of the pictures of the dishes I posted here from Kerala. Those little black seeds which you will see are Kadugu 

I have brought some of them from my trip to Kerala so I can also cook some of the dishes I learned during my trip. It is available in some Asian shops in Germany, but mostly the Brown Mustard seeds. I brought in an Asian shop in Bremen a brown-colored Kadugu and I am using now to cook my sauteed vegetables .

Below is a packed of Kadugu, the Black Mustard Seeds from Allepey, Kerala, India.

An example of a dish from Kerala using Kadugu is a Thoran, see below those little black seeds in Papaya Thoran
