How Do I Prepare Jerusalem Artichokes?
Preparing Jerusalem artichokes is relatively simple. To start, scrub the tubers clean and trim any rough or bruised spots. Then, peel or scrub off the thin skin, depending on your preference. Jerusalem artichokes can be cooked in a variety of ways, including roasting, boiling, steaming, sautéing, or mashing.
When cooking Jerusalem artichokes, be sure to adjust the cooking time based on their size and desired level of doneness. Smaller tubers will cook more quickly, while larger ones may take longer. It’s also important to cook them until they are tender, as undercooked Jerusalem artichokes can be tough and unpalatable.
Can I Grow My Own Jerusalem Artichokes?
Yes, you can grow your own Jerusalem artichokes! These plants are relatively easy to cultivate and require minimal care. To get started, purchase tubers or seeds from a reputable nursery or supplier. Plant the tubers in well-draining soil in the fall or early spring, spacing them about 12-18 inches apart.
Jerusalem artichokes prefer full sun and consistent moisture, but can tolerate some drought. As the plants grow, provide support using stakes or a trellis to keep them upright. After the first frost, harvest the tubers by digging them up carefully, making sure not to damage them.
Are Jerusalem Artichokes Good for Me?
