Traditional sour cream is made with a bacterial culture that sets at room temperature. It is probiotic and delicious. Perfect for tacos, pierogies and more!
1/4cup of mesophilic cultured dairy (see the section above for different culturing options)
1cup whipping cream (30-35% milkfat)
Instructions
Mix the culture and cream in a clean glass jar.
Loosely screw on the lid and leave it at room temperature (around 22 C, 72 F) for 12-24 hours.
Once it has thickened and tastes sour, store it in the fridge and finish it within 3 weeks.
Notes
You can find mesophilic dairy cultures in most grocery stores (eg. buttermilk). See the section above for more detailed information.
The first time you make sour cream it may take a little longer to achieve a sour flavour. It will depend on the quality of your culture. However, once you’ve established your culture, it should be relatively quick.
The cream will thicken as it cultures, but if you want a really thick sour cream, then strain it through a coffee filter (like Greek yogurt). Store-bought sour cream contains a bunch of added ingredients to help thicken the cream, so don’t expect your homemade sour cream to be as thick.Â
