Merguez is a spicy north african sausage that is popular in morocco. They are grilled and rather easy to make from ground lamb or beef, or a mixture of the two. In morocco, you can buy fresh merguez sausages in skinny three-inch links. When making merguez at home, you can feed the mixture into sausage casings or simply shape it into patties or cylinders. You will want to have merguez spice mix and harissa (a spiced chili paste) on hand. They contribute to the sausage's signature taste and color. Feel free to make your own merguez spice mix or use store-bought. As with any sausage, fat is the key to creating the best flavor and texture. Try not to skimp too much on the fat if you feel the need to adjust the recipe.
