I tried this classic shrimps in melted butter from Mrs. Beeton's tome, and I was pleasantly surprised by the simplicity and elegance of the dish. The key, I found, was in the butter—it needed to be velvety smooth, and the technique of gently simmering it with the shrimp was a delightful reminder of the old ways. This recipe is perfect for the weeknight cook who craves a touch of nostalgia. The subtle heat from the cayenne and the rich, buttery sauce create a harmonious blend that elevates humble shrimp to a sophisticated level. I ended up adding a touch of anchovy sauce to give it the finishing note I prefer. It's a quick, elegant dish that's sure to impress.
