Put a spoonful of baking soda in the glass. The dosage of baking soda can be determined according to personal taste. If it is too salty, some people can't stand it, so put less. Then fill it with mineral water to make sure the water is cold. Soda composition:
Baking soda 1 spoon
Citric acid 1 spoon
Boiling water 1000cc
Exercise:
Add baking soda and citric acid to the water to complete the original soda water.
The soda water made in this way has no taste. You can add sugar and juice according to your personal preference. People who don't want too many calories can add sugar instead of drinking low-calorie soda like me.
Baking soda and citric acid can be bought in chemical companies, both of which are very cheap materials. A catty of baking soda 16 yuan, a catty of citric acid and 37 yuan. If you want to make an advanced version of soda water, just like soda water on the market has various flavors, buy some food-grade food flavors, as long as you can find all the flavors you want.
My soda is made of strawberries and sugar substitutes, and with ice cubes, it is a great strawberry soda. Although this homemade soda doesn't have the strong bubbles of soda on the market, it tastes much smoother, only with a slight tingling between the tongues and a slightly salty alkaline taste, which feels very special.
