Iceberg Lettuce
I like curly, dark green leaf lettuces — my husband thinks those qualify as bitter. He could easily live life with no lettuce except iceberg — though I keep trying to convince him that the nutritional aspects and flavor of that are pretty much nil. Our salads tend to be mixtures that often lean a little heavily on Romaine, the chosen lettuce of compromise. I’ve been occasionally putting some produce out for the backyard deer who comes to visit — an extra ear of corn that we cooked and didn’t eat, some bok choy that was beginning to turn slightly yellow around the edges, rinds of watermelon or cantaloupe. I had just bought some new iceberg and there was part of the old head left so I added that to the deer’s offering, along with some whole wheat bread as an experiment. She ate everything — EVERYTHING — except the iceberg lettuce. I rest my case. My husband says I should have added Thousand Island dressing.
Try butter leaf. I try to buy it with the roots on so I can add water and keep it longer.
