Turn your dairy containers upside-down
How many half-used tubs of sour cream have we thrown away? This may seem a bit strange, but it’s a great way to keep our sour cream or cottage cheese fresh for a longer period of time. It’s as simple as turning the tub upside-down.
Turning our tubs over creates a vacuum within our cottage cheese and sour cream containers. This reduces the bacteria’s growth and keeps our food from quickly rotting. We can skip this part of the dairy aisle next time we go shopping.
