I tried this vintage parsley sauce, expecting a mere drizzle of green, but I was delighted to discover a rich, creamy concoction that stood out against the muted tones of my mutton chops. The blend of sauces — mushroom ketchup, cavice, and Reading sauce — created a depth of flavor that surprised me. I found the chili vinegar added a pleasant, subtle kick, a delightful contrast to the buttery bechamel base. This sauce would be a hit with anyone seeking to elevate their weekday meals with a touch of historical charm. It's surprisingly simple to prepare, despite the array of ingredients. The minced parsley, once scaled and finely chopped, ties the whole dish together beautifully. If you're looking to add a dash of Victorian elegance to your modern table, this parsley sauce is a delightful place to start. Serve it with roasted meats or vegetables for a true taste of the past.
