Buttermilk Starter Culture - ORGANIC Cultured buttermilk is sour milk used in cooking, especially biscuits & pancakes. It can also be consumed as a beverage, which we find incredibly refreshing! This culture will make thick & creamy buttermilk (cultured buttermilk is different from the thin buttermilk that is a byproduct of butter-making). It is teeming with enzymes & high in potassium, vitamin B12, calcium, & riboflavin. This buttermilk is cultured using cold milk, & fermented at room temperature. in about 18 hours it will have set, & then is refrigerated for further setting. By setting aside some of the buttermilk from each batch to make your next batch, this culture should last you indefinitely if well taken care of. We supply FRESH yogurt starter cultures shipped Priority Mail in the US (which includes delivery confirmation), enough to get you started making 2 cups of yogurt for your first batch. Make once a week to sustain viability of the yogurt starter culture. Instructions will be provided through a direct internet link.
