Now I’m thinking I should buy it and make some homemade butter.
One bit of advice. If you decide to try making your own butter, don’t use anything that’s labeled “Ultra-Whipped” or that contains carrageenan or other gelling agents. However it’s labeled, it’s not whipping cream. It’s “cream-like product”. It won’t turn into butter when you whip it the way real heavy cream does.
Hereabouts Dean’s Heavy Whipping Cream, the stuff in the purple container, is the most readily available version of real, honest-to-gosh whipping cream. I don’t use anything else. It’s a bit more expensive than the “cream-like product” but it’s worth it. If it has any ingredients other than cream in it, don’t buy it.
And you can, in fact, make butter by whipping it.
