Cooking food over fire is what made us human, and fire is still the primary means of heating food around the world. Since Memorial Day is just around the corner, marking the official start of summer and grilling weather in the United Sates, we're reprising our Your Shot grilling collection from last year to remind you that there’s so much more than burgers and hot dogs on the grill. From pigs heads in Mexico, to octopus in Greece, to sweet potatoes in Laos, check out this visual tribute to cooking with fire.
