Channa masala is a no-brainer when you’re ordering Indian takeout, especially if you’re a vegetarian. The Punjabi chickpea curry is a tantalizing balance of spicy, tangy and sweet, and it happens to be nutritionally unimpeachable. It also seems like one of those dishes that’s so uniquely flavored and intricately composed that it’s totally worth it to pay an expert to make it for you instead of endeavoring to make it yourself.
But this is a false impression that stems from most Americans’ ignorance of South Asian cooking conventions. Technique-wise, channa masala is as simple as any other stew; it requires chopping, simmering and stirring. What makes homemade channa masala challenging is getting that balance of spice, acidity, and sweetness right. I have seen many recipes that purport to be simple yet authentic, containing only seasonings easily obtainable in American supermarkets: garlic, ginger, jalapeño, turmeric, cumin, coriander and lemon juice. Such recipes yield adequate chickpea curries — but they taste nothing like restaurant channa masala. That’s because making authentic channa masala requires a few ingredients you can’t get in American supermarkets: specifically, channa masala spice blend, and amchoor powder.
Channa masala spice blend sounds like a copout, right? But it’s only as much of a copout as curry powder, or garam masala (of which you’ll need a spoonful for this recipe), or za’atar, or any other more common packaged mixture of ground spices. It is simply a combination of the spices commonly used to make channa masala. There is a valid argument that freshly ground spice blends have a stronger flavor than the packaged kind, but what you lose in potency, you gain in convenience. (That said, you can certainly make your own if you prefer — and if you don’t mind having lots of leftover asafetida, pomegranate seed powder, and fenugreek on your spice rack.)
Channa masala spice blends typically contain some amchoor powder, a sour dust made from under-ripe green mangos. But you will need to buy more amchoor powder, because it is what gives channa masala its pleasant tartness. Substituting lemon juice for amchoor powder, as is often done in Americanized channa masala recipes, is like swapping in a synthesizer for Hendrix’s guitar in “Purple Haze” and thinking no one will notice.
