Thai yellow curry paste ( Gang Ka-ri)
Yellow curry came to Thailand from Southern India. The Indian word Kari means curry. Hence Thai people call the yellow carry " Gang Ka-ri".

Turmeric powder, a common Indian spice, gives this curry its vibrant yellow colour. However, Turmeric powder was not commonly available in the kingdom in those days. So an Indian spice mix called " Ground Ka-ri spice Mix*" was made available. This spice mix consists of Fenugreek seeds, Fennel seeds, Coriander seeds, cloves, cardamon and Turmeric Powder. The Ka-Ri spice mix is then added to some basic Thai herbs and spices to make a yellow curry paste. This was probably the first Thai-Indian fusion curry.
The recipe below, I use " Ka-ri spice mix' ( Pong Ga-Ree), which is available in Thai / Asian supermarket. Failing that, grind together the list of spice above and proceed on with the recipe.
