How to make meatball style food that keeps its shape How to preserve shape of meatballs and mince-meat shami kebabs? What ingredients help these items keep their shape? We tried chicpea flour, eggs but the bodies do not keep their shape but some chefs make it so solid that you can literally throw it to someone to catch and it will not loose its shape?
Overworking the meat is generally what you want to avoid for a burger, but in the case of kebab meat it may help. It will give it a denser and bouncier texture.

To do this, when mixing in the other ingredients, just mix for a bit longer than you normally would, especially with your hands as the heat will probably melt the fat slightly and help to bind it. Keep working it until the texture is smooth.
