What is wrong with that? The thing is- store ice cream gets shipped and then sits on store shelves. It really has to be a little different than the stuff you make at home. We had some home made ice cream from the back of someones freezer once- and it was just plain wrong.
Not for decades. And your cite says not used hardly at all.
Yes, since you cant taste the tiny amount of gums they use to stabilize the Ice cream- and some use natural gums from seaweeds.
Yes, good point. But not the presence of gums.
Yep. But even that stuff- while great- cant sit in the freezer for an extended period.
