Pot-in-Pot (PIP) refers to the practice of cooking multiple dishes at the same time in the cooker. This is accomplished by using the steam rack, and an additional heatproof pot that fits in the inner pot to cook two dishes at the same time. Typically, one dish is cooked directly in the inner pot, while another dish is cooked in a smaller pot that rests on the steam rack. The ability to cook multiple items at the same time is yet another way Instant Pot® makes cooking fast and fun!
