Home Made Ice Cream (2015– ) in Pastry & Baking Posted 17 hours ago If it wasn't clear I have no love for ultra pasteurized dairy products. I avoid them whenever possible. Carrageenan (or perhaps carrageenan and glycerides) in ultra pasteurized cream is disgusting because at best the cream ends up like snot. I have never, ever seen ultra pasteurized cream for sale without carrageenan and glycerides as additives. I linked the Edible Toronto article only to demonstrate ultra pasteurized cream was readily available in Ontario, if not in Ottawa. But I have nothing against carrageenan per se. I sleep with a bag of carrageenan in my bedroom.
