Until a few years ago, with only a little effort, I could find whipping cream and heavy cream without carrageenan and other undesirable ingredients in grocery stores. Now my source has dried up. How can I obtain cream that consists of nothing but cream? I typically only need small amounts and not all that frequently. I don't imagine I can just drive up to a dairy, knock the secret knock and whisper "psssst...where do you keep the good stuff?"
You might check with localharvest.org and find a CSA (Community Supported Agriculture) farm in your area. That is if you live in the U.S. Not sure if this type of thing is available in other countries, but I wouldn't be surprised if it is in some form.
The local harvest website has a search form where you can type in your zip code to look for CSA farms in your area.
Also, in my area I can get cream at natural foods groceries and at food co-ops. So you might check on those options in your area.
Organic Valley Heavy Whipping Cream (NOT the Ultra). I had to get my local health food store to special order me some, but they were very nice about it. I used one right away, then froze the rest. I've read frozen cream doesn't whip good, but I'm using it mostly for sauce anyway.
BTW, I found Organic Valley by doing a label search for heavy creams. Organic Valley was the ONLY one I could find without carrageenan.
Skim the cream off the top from the fresh raw milk you buy from a local farmer. I know it isn't as convenient as going to the store, but getting to know some real farmers can lead to other sources of good fresh products, like eggs, and grass fed chickens/ beef. If you buy in bulk, it can be cheaper, too.
You kinda have to network a bit. I am sorry it isn't easier, but the food chain in our 'modern' western world is seriously compromised.
