You can't cook porridge in a beaker, but you can stew porridge. It can't be heated, and its working principle is heat preservation to reduce heat loss in the cup. After boiling water is added to the stewing beaker, the heat loss of boiling water is slow, and the food in the cup is cooked in the cup at a temperature similar to that of boiling water. Unlike the porridge we usually cook, the porridge made by stewing beaker will also taste different from that cooked. It can be compared with instant noodles and can be used as a reference according to the taste difference between cooked instant noodles and instant noodles.

Pay attention when using a stewing beaker.

1. The food made by stewing beaker needs to be stewed for a long time, and the food is relatively easy to breed bacteria when placed in a warm environment for a long time, so pay attention to the use time.

2. There is no guarantee that the food will be cooked by stewing the beaker. According to the laws of physical thermodynamics, energy is conserved. We know that heat can only be transferred from high-temperature objects to low-temperature objects. There is only the heat of the boiling water just added in the stewing beaker, and no other heat energy is added. If the heat preservation effect is not good or the food is difficult to cook, the food will be uncooked for a long time.
