Now comes the most important part of the procedure.
We put another piece of aluminum foil on top of the beets and bend the protruding ends of the aluminum foil on the sides of the tray, thus creating a kind of closed, tight package, inside which the beets are with all the ingredients and the juice does not leak out.
Put in a heated oven and bake at a temperature of 200 degrees for 60-90 minutes (it all depends on the size of the beet).
