Best sour cream EVER!

Bought this culture on a whim because I like store-bought sour cream. I was very pleasantly surprised when I made this with a quart of grass-fed cream from a local farm. Their "cream" has a fat content more like half and half. But when cultured, I had the thickest, richest, most delicious sour cream I had ever tasted. Thank you for the best sour cream I have ever tasted.

Delicious yogurt

Delicious from the start, but I had to play around with the amount of half-and-half and starter. I especially like 3 packages of starter to half gallon of dairy. I also find it helpful to culture overnight in my oven with the light on. This makes a sweet-tangy sour cream that is thicker. I do not stir the final product. I scoop off the top heavy cream part of the sour cream for crème fraîche like product. Then the remainder of the sour cream is not as fatty which I prefer.

In Ill., we only have UP products. After several attempts(using prescribed recipe),found the following> 1. UP 1/2-1/2 Cream, warmed to 90*, added five drops of 'rennet' in cool-down to 86*,then spread/ added C30-incorporated! 2 Works GREAT-Better than any S.C. bought locally.

made super tasty sourcream!

I used the raw milk from our own cow, let it sit overnight, skimmed the cream, added the culture per directions, let it sit overnight and by the next day was delicious, better than store-bought, sour cream. This culture was super easy to use.
