Peanuts soaked in vinegar usually use cooked peanuts, because the cooked peanuts have been cooked and have a softer, waxier texture and are easier to taste. Moreover, the skin of cooked peanuts is easier to peel off, making it easier to taste. Raw peanuts need to be cooked or fried before they can be eaten, otherwise the taste will be harsh and hard. Therefore, in order to achieve a better taste and flavor, it is recommended to use cooked peanuts to make vinegar-soaked peanuts.
