Melt the butter in a skillet over medium-low heat. Once the butter is sizzling, add the lobster meat. Increase the heat to medium and sauté the lobster until some pieces are golden and crispy about 4 to 5 minutes.
Add the vinegar to the pan. It will quickly release a sharp, intense aroma. Allow the vinegar to cook for about 2 minutes or until the overwhelming pungency fades.
Pour the cream into the pan. Season it with a large pinch of salt and some freshly cracked black pepper. Stir the lobster to coat it in cream, then let the sauce gently bubble until it leaves a track in the pan, about 2 to 3 minutes. Remove the pan from the heat, adjust the seasoning to taste, and serve immediately on top of fries, buttered toast, mashed potatoes, or anything else you like.
Notes
The measurements listed are a good starting point, but feel free to use more or less of any ingredient listed.
I've listed this recipe as one serving; however, you can divide it into two.
Add salt and pepper gradually and taste as you go.
Storage
Store any leftovers in an airtight container in the refrigerator for up to two days.
Reheat gently over low heat to avoid curdling the cream or overcooking the lobster. Adding extra cream during reheating can help maintain the sauce's texture.
