The scape is the stalk that grows from the centre of the stem, and is the beginning of the flower and eventually, seeds. However, common practice in growing garlic is to snap the scape off to focus all of its energy into developing the bulb and cloves.
Scapes are delicious grilled up with other vegetables, cut up into a salad, or made into a pesto. We use a mortar and pestle to grind them up and add to some olive oil and balsamic vinegar to make a delicious bread dipper or salad dressing.
If you haven’t tried scapes before I definitely recommend picking some up at your local farmers market and giving them a try. You certainly won’t regret it.
