Can you freeze aioli sauce?

yes, put in zip lock freezer bag or just a plastic tuppleware container which is what i do , and freeze.you should really use it after one month or less for quality.

Yes, but it is best to thin it a little with clear water first.

yes it can I do it all the time No need. I have some in the refirgerator I made 2 years ago and it's delicious. It WAS covered with a 1/2" of olive oil!

you can but i advise you not to cause you won't like after a certain amount of time.

Yes. It doesn't matter also how you freeze the meatballs and sauce. ;)
