Some suggestions on making delicious roasted coffee

For the thicker the coffee powder, the more inefficient the extraction of coffee by water and the less flavor of the coffee itself, any cooking method that will store the hot coffee for a period of time will greatly reduce the flavor of the coffee. A coffee maker plugged in at home is not a good choice. The cooking pot will cause the aroma of the coffee to be lost with the steam, leaving only the cleaning of the thick coffee cooking equipment, the purity of the water quality, the roughness and fineness of ground beans, the freshness of roasted coffee, the ratio of coffee powder to water, and the length of contact with water will affect the taste of a cup of coffee. The Coffee Cooking Association standard is that a pound of coffee powder can produce 40 to 45 cups of coffee (with a capacity of 150 ml). In Latin America, deep-fried, ground coffee usually produces 30 cups of coffee
