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.
If this all seems like too much to remember, there is an alternative: buttermilk powder, which you can find in your grocery store. Basically dehydrated buttermilk, buttermilk powder has an admirable shelf life, almost indefinitely on the shelf unopened and up to a year and even longer after opening when stored in the refrigerator.
