1, pressure cooker cooking rods (corn) need to cook about 8 minutes. Pressure cooker to cook things faster, the principle is through the liquid at higher air pressure boiling point will be raised this physical phenomenon, the pressure on the water, so that the water can reach a higher temperature without boiling, in order to speed up the efficiency of stewed food.

2, with a pressure cooker to cook corn first corn outermost thick skin peeled off, leaving the innermost 2 layers of thin skin, remove the corn whiskers after washing. Put the corn into the pot, add water, not over the surface of the corn, high heat to boil, add salt, cover and cook for 8 minutes. Sweet corn and sticky corn mature at different times, so if cooking in the same pot, after 8 minutes of cooking, remove the sweet corn first, then continue cooking the sticky corn for another 2 minutes. (That is, sweet corn cooks for 8 minutes, sticky corn cooks for 10 minutes.) Just chuck out the corn as soon as it's done cooking and place it in a colander to drain.
