Eggs and coffee can be eaten together. These two foods are incompatible. Drinking coffee in the morning really helps to keep a clear head and full of energy, but you can't drink coffee on an empty stomach, because coffee will stimulate the secretion of gastric acid, and you must eat breakfast to drink it, otherwise it will easily damage the gastrointestinal function.

There are three ways to make black coffee, so there are three different types of coffee pots: traditional filter, siphon and electric. Traditional filters are the most primitive and simple tools. The coffee pot consists of a funnel, a filter paper and the container below, but it requires high manual technology. If you grasp it properly, you can cook the best coffee with mellow taste. This kind of pot is very cheap, you can buy it for more than ten yuan. The brewed coffee pot is suitable for people who drink coffee, with stable hand feel and sharp taste. It is important to pay attention to whether it is a three-hole or a one-hole coffee set. The dripping speed of three holes is faster, the extraction time is shorter, the coffee is lighter, and the opposite is true of one hole. Siphon uses the siphon principle. Under the burning of alcohol, when the water temperature in the lower container reaches 92℃, the water flow is sucked into the upper container together with the coffee powder. After soaking and stirring, the coffee returns to its original way. Due to the addition of a stirring process, this method of black coffee has a strong flavor, but it is relatively simple because it does not require manual skills. The market price of this coffee pot is mostly one or two hundred yuan. The price of electric coffee pot is comparable to that of siphon coffee pot. It uses electricity to boil water and then soaks it. This is the easiest way to make black coffee, but because it is made with boiling water, the taste is slightly inferior.
