According to the International Dairy Foods Association, mint chocolate chip is the 10th most popular flavor of ice cream, and comprised 3% of all ice cream sold in 2000.
The popularity of the flavor has led to its use in other foods (such as cookies and meringues) as well a number of products such as cosmetics, air fresheners, and even personal lubricants. Ice cream manufacturer Baskin-Robbins has created a hard candy named "mint chocolate chip" that tastes similar to their ice cream of the same name (which is one of their "permanent flavors").
Some brands name it chocolate (or choco) chip mint, mint 'n chip, or just mint chip. It is also known as peppermint bon bon, mostly in Minnesota and Wisconsin.
