I'm sure there are markets that sell garlic scapes, garlic's firm flowering stalk, but mostly it seems a specialty item, and so the gardener's treat while the bulbs continue to develop.
It's my second year growing garlic and I've found that the best way to prepare the scapes is to roast them. Coat them in olive oil and a little salt. Toss them and then cook in the oven on high heat until they wilt and brown.
Raw, the scapes are firm on the outside and gel-like inside. Without roasting, the mouthfeel is a little too unctuous and the garlic flavor is subdued. Roasting concentrates the flavor, improves the texture and makes them easier to chew. Because of the tough, long fibers in the skin, cut the scapes into bite-size pieces.
This high-heat roasting method is one I often use for green beans and asparagus. Usually, the beans or asparagus are cooked at 500 degrees for just a few minutes. At 500 degrees, burning dinner is too easy, so for these scapes (which I only have so much of), I set the oven to 400 degrees instead.
ROASTED GARLIC SCAPES
1. Preheat the oven to 400 degrees and toss two-inch garlic scape pieces with olive oil and salt in a bowl.
2. With your fingers or tongs or chopsticks, transfer pieces onto a baking sheet with raised edges. Don't pour them out from the bowl because you don't want excess oil on the sheet. Space the pieces out and try to put the thicker sections at the edges of the group.
3. Put the baking sheet in the oven (middle rack is fine) and stay in the kitchen. After about 5 minutes, check the pieces. If they are lightly browning and starting to smell aromatic, mix them around a little bit and roast more, checking after about 3 minutes or so. If they aren't browning, just give it more time, checking every two to three minutes or so.
4. Take out when a majority of the pieces are browned and wilted, 10 minutes maximum (though every oven is different). Use as a garnish or in pasta, frittata, in tacos, on pizza (put it on last minute) or rice dishes.
(If you want to try roasting green beans, asparagus or garlic scapes at 500 degrees, you'll get crazy dark marks which translates into flavor. One step too far, though, and your food is burned. To do the scapes at 500 degrees, consider parboiling first. Pat dry and then continue on as above. Cooking times are a lot quicker though. Check after a minute and a half. Definitely don't leave the kitchen!)
