DIY Sour Cream
Sour cream is the delicious base for a variety of dips and sauces, and making your own couldn't be easier. All you'll need is a small amount of store-bought cultured buttermilk (1 percent is fine), a pint of heavy cream and a container large enough to hold the cream. To start, pour 1/4 cup of the buttermilk into the bottom of the container.
