It's no secret that I just love things of terra cotta -- so spotting these jugs in the middle of Jefferson's garden compelled me to investigate!
There were about a dozen of the pots in all ... some 'at work' and some put to the side as though their 'job' was finished.
We asked the gardener about them.
"They're blanching pots," he told us. "Jefferson would place them over the kale as it was growing to 'whiten' the green leaves as they grew." Apparently, white leaved kale is a delicacy and believed to be sweeter than the normal green leaves.
I had heard of blanching asparagas and other vegetables -- but not kale -- and NOT with such beautiful pots!
