Cut lobster into chunks. In a frying pan, sauté lobster in butter for 1 minute. Add vinegar and stir. Add cream and stir until hot. Season to taste.
Note: If making Clara Harris's Hot Lobster Sandwich, serve on top of (and between) 2-4 pieces of toast.
Tip: Can substitute 1 tin frozen lobster, thawed and drained, for fresh lobster. (see p.52)
