Preparing: Be sure the tough part of the scapes and raab are broken off (they generally break at the tender point like asparagus does). The rest is easy: saute vegetables in olive oil. Add a bit of the pasta water before stirring in the pasta.
Eating: Top with parmesan cheese and fresh lemon juice.
Dish history: Early garlic scapes and raab are harvestable at about the same time. The best part about scapes is that you get a similar garlic taste to your dish, but you don't have to peel and mince any garlic.
