In Japan, pork loin is relatively cheap and often goes on sale. One of the small-sized pieces of meat are great for a 2-person dinner with leftovers for lunch the next day. I love the flavors in this recipe, which I originally saw here.
1 small pork tenderloin
1 tsp salt
1/4 tsp pepper
1/2 tsp each cumin, chili powder, and cinnamon
1/2 cup brown sugar
1 tsp chopped garlic
1/4 tsp chili oil (In Japan I use ラー油, raayu.)
Preheat the oven to 180C/350F.
Mix the salt, pepper, cumin, chili powder, and cinnamon in a small bowl. Rub the spices all over the outside of the pork tenderloin. In a skillet over medium-high heat, brown the pork on all sides. Then place in a small oven-save pan (use something with edges).
Mix together the brown sugar, garlic, and chili oil. Spread the mixture evenly over the top of the pork tenderloin.
Bake for 25 minutes until cooked through. Let meat rest for 10 minutes before slicing.
