When buying a lobster, look for one that is active and heavy for its size. A fresh lobster will provide the best flavor and texture. Although there are traditional vegetables used, you can use other types as well such as broccoli, carrots, and baby corn. Should you have leftovers, store them in an airtight container in the fridge but no longer than 2 days. Reheat gently on the stovetop to avoid overcooking the lobster.
