Garlic scapes are the stem and flower bud of the garlic plant. Farmers remove the scape in the spring to prevent flowering, because the plant will then produce bigger cloves of garlic. Scapes can be eaten raw or cooked, and they have a lovely mild, fresh green flavor. Making the aioli by hand with a mortar and pestle takes only about five minutes and is immensely satisfying. If you’d like to use a food processor or immersion blender instead, then double the recipe in order to create enough volume for the machine.

2 tsp. finely chopped garlic scapes
Zest and juice of one lemon
1/4 tsp. fine sea salt
1/2 tsp. Dijon mustard
1 egg yolk
1/4 tsp. white pepper
1/2 C. extra-virgin olive oil
2 tsp. tarragon, chopped

In a mortar and pestle, pulverize the garlic scapes, lemon zest, salt and mustard until it begins to turn a pale green color and there are no longer large pieces of garlic scape. Add the egg yolk, lemon juice and pepper, and mash until uniform. Drip in the olive oil while mixing. Begin slowly and work your way to a steady drizzle. If the oil begins to separate, stop pouring midway, increase your stirring for a second, and then continue. It should be pretty thick and a much paler green than what you started with. Adjust the flavoring as necessary, adding salt, lemon juice or pepper to your taste. Fold in the tarragon and serve. The aioli will keep in the refrigerator for approximately one week.
