How to Care For Iceberg Lettuce
A head of iceberg lettuce requires slightly different handling than other less densely packed varieties.
1 Remove the core by sharply knocking the head, stem down, against a countertop or cutting board until it's loose.
2 Twist the stem until it pulls out easily. Discard the core, along with the outer layer of leaves.
3 Rinse the whole head of lettuce well under very cold, running water and shake it dry over the sink.
4 Wipe off the excess water with a clean dish towel or paper towels.
5 Wrap the whole head in paper towels, place it in a zip-top bag, press out the air, seal it, and store it in the fridge.
6 Keep it up to a week, maybe even a few days longer, ready to pull off a few leaves for sandwiches, shred finely to top tacos or nachos, or cut off a wedge to eat with blue cheese dressing.
