I batch cook and freeze meals, and some of them look similar (sauce and chicken vs sauce and pork) and I want to eat the older stuff first. There are also some products that are recommended to be disposed of within X days of opening, which fall well before their best by date.

When I batch cook meals, I then eat them over the next few days until either it's done or it's been too long for that meal. Then I batch cook something else. I usually don't have multiple batches on the go.
