The pasta section at my TJ's has been a bit sparse of late. Shelves are completely filled but a lot varieties are missing. No spaghetti or fettuccine for some time. Dan Pashman's said that the TJ's version of cascatelli is in stores but may take a while to make it to all locations, particularly on the west coast. I haven't seen it here yet. I'll continue to check.
I did purchase this fusilli corti bucati recently. Like bucatini, the little spiral shapes are hollow so they cook quickly - the package says 7-9 minutes. In my hands, 7 min was plenty and I'd go with less if finishing will take more than a min or two.
I saw someone recommend them for soup. To my taste, they're a little big for that but maybe I should try before deciding that.
Here they are with hot sausage, baby kale and Parmesan from a recipe adapted from Julia Turshen's Small Victories (she uses orecchiette and baby spinach):
In addition to the named ingredients, this dish gets its flavor from caramelized onions and lemon zest.
