I read once (a long time ago) that lettuce/salad stays good longer in glass jars than in the plastic bags salad comes in. I kept meaning to try it and kept forgetting about it. A few weeks ago I remembered to try it and I took pictures to share the results with you!
First, you should know that I normally put a piece of paper towel in my bag of salad once it has been opened. I've found that putting the paper towel in there helps absorb moisture which would make the salad soft faster anyway. So I already had some success in that area.
To get reliable results, I decided to keep some salad in the bag, with the paper towel, just like I would normally do, as a control group.
After about a week, here's what I had:
About 20% of the bag was getting that dark, wilted, rotten aura. This is about normal for me with this time period in a bagged lettuce.
The jarred salad was 100% fine.
I will say, the jar stank! I guess in the bag the smell of greens has a chance to dissipate a bit. But in the jar it's trapped. Be prepared when you open it, the smell will be strong, but will last just a few seconds.
I decided to put the lid back on the jar and put it back in the fridge to see how long it lasted. I got about another week out of it before it started to turn yucky.
So final results:
-bagged salad in bag with paper towel - 1 to 1 1/2 weeks
-salad in glass jar - 2 to 2 1/2 weeks
I'd love to know if any of you have tips on keeping fresh produce fresh longer. Please leave them in the comment section if you do!
