1, how long a dish can be cooked depends mainly on the temperature of the cooked dish. If it is a fire, the water will be cooked in about half a minute after boiling. If you want to eat soft vegetables, you can cook them for up to one minute. When cooking vegetables, be sure to clean them first and soak them in salt water before cooking, so as to remove the pesticides and bugs left in them and make you feel more at ease.

2. Green vegetables are one of the vegetables that are particularly easy to cook. Therefore, whether you are cooking or frying vegetables, you must master the heat and time, and you can turn off the fire when you are interrupted. Too ripe vegetables will affect its taste. At the same time, when cooking, add a few drops of white wine before serving. Because alcohol in liquor reacts with organic acids, the content of organic acids will be reduced, so that magnesium in chlorophyll will not be replaced, thus maintaining the green color of vegetables, so it looks appetizing.

Also, be sure to put some edible salt before cooking. You can't dehydrate the vegetables after cooking, because the salt is put in early and the taste is not crisp. This needs attention and cannot be ignored.
