Whether the shashlik will turn out tasty depends not only on the quality of the meat, but also on the marinade.
We'll tell you a recipe for a marinade that will make even the breast melt in your mouth.
There are only two main ingredients: mayonnaise and onions (two to three onions per kilogram of meat).
You also need to add salt and black pepper.
Cut the onion into half rings, add salt and pepper, then mash with a potato masher.
Add meat, pour in mayonnaise (2/3 of a regular package), mix well and put in the refrigerator for several hours.
