Start by roasting the walnuts and roasted gram dal together in a pan over medium heat until they turn golden brown.
Keep stirring constantly to avoid burning. Once the walnuts and roasted gram dal are roasted, remove them from the pan and set them aside to cool.
In the same pan, dry roast the red chilies, garlic cloves, cumin seeds, and curry leaves until they are aromatic and slightly browned.
Let the mixture cool completely before grinding all the ingredients together into a coarse powder using a mixer grinder or food processor. One important tip is to pulse two to three times to avoid over-clumping, as walnuts do have a higher fat content than peanuts.
