Question: what is the difference between ultra pasteurized and pasteurized cream?
Answer: Pasteurized cream has been heated to 167 degrees for 15 seconds, then chilled. ... Ultra-pasteurized cream has been heated to 280 degrees for two seconds and then chilled. This gives it a longer shelf life — up to 60 days, unopened. But it won't whip up as easily or hold peaks as long as standard pasteurized cream.
