The Kuntz Spoon is a large sauce spoon developed by Chef Grey Kuntz. It's a tool found in the knife rolls of many a line cook world wide.
Chef Kuntz was known for being exacting and having a standard size spoon for portioning sauces and other components helps keep quality consistent in a fine dining kitchen. The large spoon is great for sauce work and plating and some cooks will even use it in place of a spatula when working a grill or sauté station on the hot line.
The Kuntz spoon comes in different sizes and both male and female formats. It's not hard to find knock off versions of the spoon out there, and for most kitchens, simply having several large spoons will suffice.
