How long do you have to wait before you eat them?

You watch and see when it stops making bubbles. Most veggies take about a week or ten days. You can taste them every 2 or 3 days to see how they taste. When you put them in the fridge it stops the fermentation process.

What is the importance of probiotics?

The recipe is almost the same as something called ”syra grönsaker” (leaven vegetables) in Sweden. The difference is that you also add some milk acid bacteria to the mix. I once heard that leavening is the only thing you can do to fresh vegetables that make them more healthy.

Is this different then pickling?

Yes, a little different. When you pickle, you add vinegar too.

#6 Oh okay thanks! I wonder which has a better taste 

#3 Probiotic's are healthy bacteria for your intestines. Kind of like yoghurt.

#5 When you pickle foods you don't get the benefit of probiotic's.

#7 It just depends on what you like. If you want tangy then pickling is great. However, you can add apple cider vinegar to fermented foods to get the tangy taste.

I made two jars of fermented red onions and they taste great! I am really like how they turned out.
