Entered for safe-keeping, by J. Kenji Lopez-Alt of Serious Eats, touted as "The Best Chicken Tikka Masala". Adapted somewhat. He gives 2 ways to finish cooking: on the grill or under the broiler. He recommends pulsing the peeled ginger and garlic in a food processor instead of box-grating them. Can't wait to try this! He recommends bone-in chicken because the meat (especially breasts) is less likely to overcook. For best taste, toast whole seeds and then grind in a spice-dedicated coffee grinder. Preparation time includes 4 hours for marination.
