Is it possible to prepare sour cream using the instant pot yogurt setting? From what I've read it maintains about 110 degrees, so significantly hotter than your recommendation in the recipe for the product.
If not, can you suggest a way to incubate without special equipment? The only thing I can think of would be to make a hot water bath in a cooler and keep the lid closed, but that might require adding hot water occasionally to keep the temp up, so that seems less than ideal
Hi Jay,
The cultures that make up sour cream culture blends are mesophilic, and won't be happy at yogurt (thermophilic) temperatures -- and if the culture's aren't happy enough to reproduce, you will not have a good result at all! The temperature recommended for incubation of sour cream and buttermilk (77F, plus or minus a few degrees) is obviously easier to maintain in some homes than others, depending on where you keep your thermostat! A Yogotherm incubator works very well, but any well-insulated container should be able to maintain a temperature that is in acceptable range. Your cooler idea is a popular one -- one tip, the less air space left in the cooler, the less you will have to concern yourself about making sure your temperature stays in range. I also know folks that have used heating pads, but those vary quite a bit so employing that method might include some trial and error.
Hope this helps!
