This is a really tasty marinade that would also go well with chicken.The pork will be slightly crisp on the outside and succulent in the middle. Great with a salad. I believe the pork fillet is called tenderloin in the US.
2 1/4 cups plain yogurt
3 tbs olive oil
2 1/2 tbs lemon juice
2 tsp salt
3/4 tsp ground cumin
3/4 tsp ground coriander
3/4 tsp black pepper
2/1/2 lbs of pork fillet
1 cup fresh mint leaves
2 tbs minced shallot
Whisk together 1 cup yogurt, 2 tbs oil, 1 tbs lemon juice, salt, and spices, then add pork and turn until coated well. Marinate at room temperature 20 minutes.
While pork is marinating, prepare grill for cooking. Use a grill pan and bring it to a medium hot setting. You can even use a barbeque but make sure the charcoal is medium hot.
While grill is heating, whisk together remaining 1 1/4 cups yogurt and 1 1/2 tbs lemon juice and salt to taste.
Remove pork from marinade (you can discard the marinade now as it won't be needed) and grill pork on lightly oiled grill rack, turning over occasionally, until just cooked through, but test to be sure that the juices are not too pink as undercooked pork can be a health hazard! Transfer pork to a platter and slice.
Toss together mint, shallot, and remaining tbs oil in a small bowl. Drizzle pork with yogurt sauce and top with mint salad.
