The One and Only Indian-ish Marinated Chicken I Make

When my cooking really impresses people—you know, those occasions when a person asks, “What is….that flavor?” while lapping up the sauce on her plate with an index finger—my response is usually the same.

“It’s the amchur.”

Amchur is the secret ingredient in the only chicken recipe I make. It’s what makes my chickpea stews complex and slightly tangy. My peach smoothies extra interesting. It’s the unassuming packet of brown stuff in my cabinet that I reach for more often than almost any other spice.

Amchur is a bit of genius in Indian cuisine for which I salute my ancestors deeply. It is mango powder, made from taking unripe mangoes, letting them dry out in the sun, and then blitzing them into a powder. The result is intense and sour. It’s a flavor that hits you right in your salivary glands and makes you want to take another bite. Who would have ever thought to turn disappointing fruit into a spice? Enterprising Indians, that’s who.

I use amchur when a dish is in need of acidity and I don’t have lime or lemon on hand. Alternately, I use amchur when I want sour with a little more depth than citrus. In Indian cuisine, amchur is often added to dishes that need tanginess but not moisture: a batter for a pakora (a spiced, fried fritter), or a filling for a samosa. Amchur is the key ingredient in chaat masala, that funky spice blend that I also put on everything. The reason you find yogurt-slathered papdi chaat or aloo tikki so craveable is probably the amchur.

The most inspired use for amchur that I’ve encountered is my aunt Sonia’s famous chicken recipe. When I say “famous” I mean famous among the 20 or so of my family members who she makes it for on vacations. It is the only chicken recipe in my cookbook, Indian-ish, because it is the only chicken recipe that I need in life. Amchur is the absolute best spice for imparting tons of flavor on the much maligned boneless, skinless chicken breast. But for years, Sonia would not share the recipe. On vacations, she would disappear into the kitchen and return with a resealable bag filled with chicken and the bright yellow marinade. None of us were allowed to know what was in it. Not even my cousin Isha, her only daughter!

I asked her repeatedly for the recipe, and finally, she gave in. That’s when I learned that what makes the chicken so great is the small but mighty teaspoon of amchur in the marinade. The amchur plays double duty in this recipe: it not only adds this pungent, lively flavor to the chicken, but because of its acid content, it also tenderizes the meat during the marinating process.

I doubt that I have even scratched the surface of all the things amchur can do. I want to mix it into a margarita for a refreshing cocktail. I want to add a pinch to softened butter and lather it onto grilled corn. I want to churn it into ice cream! Toss a spoonful into any winter stew to add a burst of brightness. What about sprinkling amchur straight onto ripe (or frozen) mango, for a mango-on-mango situation? Why not?! The winter is long and my amchur stash is large.
