Hey there. It's Ms. Late to the Party telling you to do That Thing Everyone Else Was Already Doing Anyway.
media saturation), go forth and find some! They're just going out of season now (in New England) but if you can still find some at the markets, they're quite surprising and delicious!
What to do with them: apparently you can use them anytime you would normally use a green onion, or you can saute them like asparagus, throw them in a stir fry (this would be delish), or just eat them in a salad. The most popular choice, though: make pesto.
Here's what I did:
I roughly chopped the scapes and threw them into the food processor. Then I threw in a hunk of pecorino romano and a few leaves of basil (not many). Then I processed until that was all looking sort of chunky and happy. Then I slowly poured in olive oil until I liked the consistency. (I used a half pound of scapes, probably a quarter pound of cheese, and a half cup or so of olive oil. But I didn't measure and neither should you.) This pesto is delicious over pasta and I think it would be be a nice topping for some roasted chicken (or fish, maybe?) and it's tasty spread on bread.
Also, if you didn't notice, I mentioned freezing this stuff. It's a good idea and you should try it. This stuff will keep for a while if frozen and if you squish it into icecube trays, you have the perfect dose for a bowl of pasta.
