Using fresh parsnips is key for the best flavor and texture when roasted. When parsnips are fresh, they have a sweet, earthy flavor and a tender, creamy texture. However, as they age, they can develop a tough, stringy core that can be unpleasant to eat. To ensure fresh parsnips: 1. Look for firmness. Choose parsnips that are firm to the touch. Avoid any that feel soft or mushy, as this indicates they are past their prime. 2. Check the skin: The skin of fresh parsnips should be smooth and free from excessive blemishes. Avoid parsnips with cuts or dark spots. 3. Assess the color: Fresh parsnips should have a creamy white or pale beige color. If they have started to turn brown or yellow, they may be getting old. 4. Smell them: Fresh parsnips should have a mildly sweet, earthy aroma. If they smell musty or off, they may not be at their best. 5. Avoid very large parsnips: While large parsnips may still be tasty, smaller to medium-sized parsnips are often more tender and have a milder flavor.
