The challenge is how to keep the greens fresh in the refrigerator for
the length of time it takes you to consume all of it. It’s not really a
challenge because all you need are plastic bins, paper towels, and a propping
device.
I found the ideal plastic
storage bins at a home improvement store. They serve the purpose because they
are long enough to fit a whole romaine head and deep enough to fit an average
green lettuce head.
Before I store the greens, I pluck out the compromised (bruised) leaves
and rinse the heads to remove whatever sand and dirt are stuck in there. If the
leaves are a bit limp, I soak the whole thing in water for about half an hour
to revive them. Then, a gentle shake to remove the excess water and they’re
ready for the bins.
Because contact with too much moisture promotes leaf decay, and the
bottom of the bin is where the excess water gathers, I address that concern two
ways: I put a double layer of paper towels to absorb the excess moisture in the
bin, and I install a propping device over the paper towels to hold the greens
away from the wet towels. For my romaine and greenleaf lettuce, I used a
plastic packaging tray.
That plastic tray was originally the packaging tray of quail eggs that
we bought at an oriental store. It was just what I had on hand; I could’ve used
a stack of plastic spoons or a few sauce containers. I actually used several
water bottle caps for my iceberg lettuce bin (I’m the Recycle-Repurpose Queen!).
The point is to slightly lift the greens from the bottom of the
container to allow air circulation and minimal contact with a wet surface.
The bins are not air-tight (veggies need to breathe too) but they seal
well enough to keep the greens from drying out in the fridge. Keeping them in
their own containers also ensures they don’t get poisoned by the ethylene gas
from certain fruits we also keep in the fridge.
But here’s my biggest reminder: make sure your refrigerator temperature
is set no higher than 40 degrees F (4.4 degrees C); the wrong
temperature will hasten spoilage.
Another tip: make sure the
bottoms of the lettuce heads are facing the back of the fridge. Reason: it’s
colder near the back wall of the fridge; leaf tips could freeze.
