Sustainably packaged and backed by clear activation instructions, it empowers you to craft fresh, preservative-free sour cream with minimal effort. ## Description Make your own sour cream at home with almost ZERO effort. Never buy it again. One of the best sour creams you will ever taste, strongly reminiscent of grocery store sour cream without the weird funk behind it. Review: Easy to use cultures but follow the rules - I've had some experience culturing foods, but not done sour cream or creme fraiche before (yes, this came with a packet of creme fraiche - very nice). I have to confess I'm starting again because I messed up by not making it frequently enough and not stirring my 2nd batch of sour cream properly - so, yeah, there's some fussiness with that, but standard for mesophilic cultures (heat milk to start, stir every so often & keep area clean). The flavor was good and I'm pleased. The shipping was also fast. I ordered on a Friday night, it's not a Prime order, so figured it would go out like Monday and be here sometime that week. It was shipped that very Friday night and arrived Monday. Review: Great product! - The product came fairly quickly. First batch came somewhat gritty, but second one was smooth. Just a teaspoon from previous batch is enough to produce good results. I make it in InstantPot at temperature of 86 degrees. I used heavy cream instead of recommended half and half. Way better than store bought sour cream and can be produced in perpetuity. Highly recommend. ## Features - 100% Organic Dairy with Active Cultures Our cream cultures are carefully fermented with the highest quality organic dairy, ensuring that our probiotic products are not only delicious but also packed with the beneficial bacteria your body needs for overall wellness. - In the packet, you will find approximately 1/2 teaspoon of our premium classic sour cream culture.
