You use a grill plate to prepare meat and fish at a high temperature. Because of this high temperature and the ribbed grill plates, food sears fast, it retains its juices, and gets the recognizable grill stripes. Contact grills come in different versions. So, you can completely fold out some grills into table grills and grill with several people at the same time. You can switch grills with removable plates with waffle plates, for example. And they're easy to clean.
