Tips to change the taste of cooking: when cooking, drop a few drops of vinegar into the water, and the cooked rice will be whiter and more delicious. Add some milk when cooking. The cooked rice is not only white and bright, but also has a unique milk flavor. Tips for steaming leftovers: when steaming leftovers, you can add a teaspoon of salt to the water at the bottom of the pot, so that the steamed leftovers will be the same as the newly cooked ones.
