1, washed with edible salt
Salt is an essential seasoning for cooking in every household. Although it is only seasoning, it has a good decontamination effect. Pour a little salt into the cup, then wipe it carefully with your hand or brush, and then rinse it with clear water several times, and you can easily remove the coffee stains from the cup.
Step 2 wash with vinegar
The main components of vinegar are acetic acid and organic acid, which can dissolve a lot of oily dirt, neutralize some alkaline dirt, prevent mildew, remove odor and effectively inhibit mold growth. The acidity of vinegar can react with coffee stains to produce water-soluble substances, which can remove stains. Pour some vinegar into the cup, wait for about 3-5 minutes, and brush it with a brush. The coffee stain in the cup is easy to clean.
Step 3 wash with baking soda
Baking soda is used in almost every family in daily life. It is an alkaline substance, which can remove stains, especially all kinds of residual stains. Prepare some baking soda, pour it on the cleaning cloth, drop some water and wipe it repeatedly along the wall and bottom of the cup, which can effectively remove the coffee stains in the cup.
Techniques for making coffee
1, brewing time
Brewing time largely determines the taste of coffee. Generally speaking, the longer the extraction time, the stronger the coffee flavor, the higher the concentration and the more obvious the fluctuation. On the contrary, the shorter the extraction time, the softer the flavor and the lower the concentration, and the less obvious the bitterness and sweetness of coffee.
2. Brewing water temperature
The water temperature is inversely proportional to the roasting degree, that is, the deeper the roasting degree of coffee, the lower the water temperature. So the brewing water temperature can be determined according to the degree of baking.
3. Water flow
Water flow is closely related to alcohol content. Too mellow, it will have a bitter taste; Too low, the acidity is obvious. Therefore, when making coffee, you should master the brewing water flow. Water flowing through the assembly will lead to an increase in alcohol content.
4. Proportion
Although everyone feels different about the taste and will have their own brewing ratio, we will give a general standard, a spoonful of coffee plus 150 ml hot water. As for whether you like strong or light children's shoes, just control this ratio up and down by yourself.
Step 5 add salt
Many people think that coffee is bitter or sour, and they will choose to add some sugar to neutralize the taste. However, compared with sugar, adding salt can better neutralize the sour taste and improve the taste, so we have the well-known Haiyan coffee, which shows that adding salt in the movie is also reasonable.
