Marinade: Mustard regular+tomato paste+olive. oil+liquid honey ( a little) and onion juice (you can just chop the onion in a blender and add the entire slurry into the marinade sauce)+garlic+black pepper bitter+salt. Marinade for chicken days in a cool place.

The day passed, peel the potato, cut into 4 pieces, add to the chicken, all mix well, allow to stand for 30 minutes, then put into the form all together with the marinade and put it into the preheated oven until potatoes are done at 180-200 degrees, as you know the chicken will be ready a little sooner, does not cover, but stir periodically.

And surprisingly, in this embodiment, the marinade gives the potatoes such piquancy in the aftertaste, though, produce one marinade, and the taste of the potatoes and chicken are completely different. Savory!
