I have a Ninja too. That’s definitely what I would use if I had pork rinds to grind. Maybe I’ll add some to my Walmart order I’m picking up on Sunday. I have until tomorrow to modify my order. I saw when I placed my initial order that they had Daisy sour cream, the only brand I buy. Nearly ordered some. But they say that if the item you want is not available they’ll sub something else, and I always worry they’ll sub in something crappy.
