Vinegar Soaked Banana
1.
Good brown sugar is half the battle haha! I use brown sugar lozenges made by myself in the old way. It is said that this kind of nutrient content is the highest. If not, I can buy brown sugar powder from the supermarket.
2.
Use the back of a knife to pat into powder, the more crushed the better
3.
Choose a big banana and cut into slices of equal thickness
4.
Find a clean, moisture-free bottle and pour a little white vinegar into it first
5.
Then add a little brown sugar and stir to melt
6.
Then put a layer of banana and a layer of sugar on top, add white vinegar to the mouth of the bottle, and put it in the refrigerator for a whole day.
