Preheat oven to 170 degrees. Lay a large baking dish with parchment.
Finely chop the cilantro and peeled garlic. Grate Suluguni, mix with cilantro, garlic and starch, pepper.
Make in each thigh, retreating from the skin about 1 cm, a deep incision-pocket, without cutting through.
Fill this pocket with a mixture of Suluguni with cilantro, stab with a toothpick. Lay the chicken thighs in the form of skin up. Try to arrange them so that the edge, stabbed with a toothpick, was raised and the filling would not flow.
Mix adjika with butter, grease chicken thighs with this mixture.
Cover the form with foil. Put in the oven for 30 minutes. I'm in my oven usually raise a little the temperature to about 190 - 200.
After 30 minutes, remove the foil and bake the thighs until Golden brown, another 15 minutes.
Serve hot. It happens that you do not find in your refrigerator Suluguni, then I take mozzarella, respectively, it is necessary to salt the filling a little.
