No one would sell to a bid a penny less and no one would lift an offer of a penny more. Thus there would be no trading and no stock market. We need human emotions like greed and fear to get things moving. TV series and movies are all fiction, but the chart of Vulcan Materials is all fact.
How They're Made. Sour cream is made by adding lactic acid culture to cream and sometimes milk to thicken and sour it. In France, crÃ¨me fraÃ®che was traditionally made from unpasteurized cream that naturally contained the right bacteria to thicken it.
Since creme fraiche does not curdle when boiled, it is the ideal thickener for many sauces and soups. Vegetables (particularly potatoes) benefit from a dollop of it. It is also delicious on fresh fruit, cakes, cobblers, and puddings. Commercial creme fraiche is quite expensive, so the homemade version is a life saver.
