Garlic scapes are the stalks that grow from the bulbs of hardneck garlic plants. Scapes first grow straight out of the garlic bulb, then coil. When harvested, they look like long, curly green beans. The scapes are usually harvested before they flower so the garlic plant can channel all its energy into producing the most flavorful bulbs. The resulting scapes taste mild and sweet, like chives or scallions, but with a hit of unmistakable garlicky flavor that's softer than its bulbous counterpart
The entire garlic scape is edible and you can use the whole scape in pestos and other purees.
