Recently I was doing some freezer cooking and had some extra "sauce." I wanted to save the sauce for future meals so I put it into baggies. Pouring a liquid can be tricky when it comes to getting it into a baggie. I opened the baggie and pushed it down into a tall glass. Then I folded over the top of the baggie. This helped keep the edges clean, in case of spillage! I poured from a measuring cup and had zero mess!
