No place in my area sells chicory (the lettuce)
I'm in a far-flung area of NYC but can't find a source (I want it for an exotic pesto dish). Not the supermarkets, not the farmer's market, not the local greengrocer. I find this kind of extraordinary. You can easily get escarole, Boston, romaine, iceberg, arugula, and the more exotic baby greens, but not chicory. Not even the Dean & Deluca on Broadway in NYC had it.
Have you tried Eataly? Or the Manhattan Fruit Exchange at Chelsea Market?
Come to NJ. The Shop Rite in Hoboken sells it. In fact, it's pretty common in many supermarkets in NJ.
It goes by various names, including "curly endive". You could use frisee instead. It's virtually identical to the paler, lacier leaves at the heart of a head of chicory.
Markets don't like to stock perishables they aren't positive will sell.... There can be huge variations in supermarket inventory (and prices) in manhattan just neighborhood to neighborhood.
Don't ask for chicory, just show a picture of it from google images to someone who works in produce when shopping.
Fairway on 30th st and 2nd ave had it this weekend
