A couple of weeks ago a friend called and asked what I do with my garlic scapes. She remembered that I make my garlicky sourdough bread with it and was planning ahead.

May and early June are the perfect time to harvest garlic scape around central Ohio—your area may differ. What you’re looking for are the young and tender curled tops. If a few are older and larger, simply snip off the developing head (as shown in the photo above), they’ll process in with the rest just fine.

Once you’ve snipped to your heart’s content, you’ll want to rinse off your bounty in fresh water. I usually swoosh them around a bit, then drain. However, you may want to inspect more fully since birds tend to like using these sturdy curls as perches. Give your strainer a couple of shakes and drain well.

I use my beloved, forty-year-old Cuisinart food processor (shown in the photo above) to process the scape — this is actually the fastest part of the whole process. I highly recommend cutting the scape into smaller 3-inch pieces before dropping them in the processor. If you don’t, you’ll find that the stocks don’t fall down into the blade for chopping and you end up having to dig them out later. Trust me, it’s a mess.

After you have filled your processor halfway with the pre-cut scape pieces, add at least 2 tablespoons of liquid. If your scapes are very moist — perhaps it’s rained recently — 2 will be plenty. If your scapes are drier, you may want more than 2 tablespoons. I like to use 1 tablespoon of water and 1 tablespoon of olive oil. If you are planning on keeping your pesto in the freezer longer than a year, I suggest using only water as oil can go rancid.

Process the scape until well chopped. I don’t worry about the perfect size at this point because I end up adding another load of scape — about the same amount as I just processed — to the bowl and then continue processing. Don’t forget to add the liquid to the second batch.
