Ebstein Anomaly Ebstein anomaly is a rare defect in which the tricuspid valve, which prevents backflow of blood from the right ventricle into the right atrium, is deformed. The right side of the heart is where deoxygenated blood from the body is pumped into the lungs for oxygenation.
Buttermilk never expires. Ten days after the expiration date, just boil it for a few minutes and let it settle for a while. It makes a great dry yogurt in the form of cookies. They last for years.
That said, we wondered if the flavor of buttermilk changes the longer itâs stored. To find out, we held a series of tastings, comparing pancakes made with freshly opened buttermilk with those made with buttermilk that had been refrigerated for one week, two weeks, and three weeks.
