Yu Bing had promised Xiao Li that she would give her a bottle of apple sauce. Now that she had bought the white sugar, she could start making it.
First, she would peel the apple, remove the core, and cut it into small pieces. Then, she would put it in light salt water and soak it for 15 minutes. After fishing it out, she would throw it into the pot. Then, she would put in a suitable amount of white sugar and turn on the low heat to stir.
When the apple was translucent, a little white vinegar was added. Because there was no lemon, it could only be substituted with white vinegar. After being brewed for about an hour, the apple was pressed into mush with a big spoon. Then, the pot could be lifted and the apple sauce could be bottled.
Yu Bing looked at the golden and alluring apple sauce in the glass bottle, then gave it to Xiao Li in satisfaction.
