Mix the gyros spice with the oil in a bowl, season with salt and pepper to make a nice liquid marinade.

To tie a knot at the beginning of the roast, then at the end and then in the middle. The first 3 bindings are not so tight, otherwise the filling will be pushed out. Then bind as usual, always with feeling.
Fry at 180 ° C top / bottom heat for 1.5 - 2 hours up to a core temperature of 75 ° C in a preheated open. Pour the gravy over and over again. Don`t be alarmed, the roast will shrink because the onions are also losing water.
When serving, work your way from twine to twine, the meat is cut into small pieces.
