Excellent post! I only knew some foods that went through this process (fermentation). I think that involving children in the art of cooking is great since it teaches them to eat healthy, to make the most of their food and, above all, to preserve them to taste them in another time. Not all bacteria are bad or yeast. There are people who love fermented foods but are unaware of their process. Congratulations for your post. Greetings and blessings.
