1. Prepare a pot of boiling water and a glass of cold water (or warm water). There are bowls, spoons and a packet of sesame paste. When we are ready, we will start brewing.

2. Open sesame paste and pour it into a bowl. First, pour the prepared cold boiled water into the bowl. It doesn't need much, only about one third of the bowl is enough. Then stir with a spoon. If some small protrusions are found, they will be broken by gently grinding them on the inner wall of the bowl with a spoon until they are evenly mixed.

3. Reheat the boiling water and stir. Here, add the amount of hot water according to your taste preference. If you like to drink sticky water, put less water. If you want to drink thin water, put more hot water.

4. Finally, stir evenly with a spoon. This sesame paste is smooth, without any massive precipitation, and tastes excellent. This is the trick of cold water before hot water.
