We've never had oyster stuffing. Have you? Whoa, it's a lot of work if you're talking about shucking dozens of fresh oysters to chop and bake with your bread cubes. But the payoff (we hear) is that the bread soaks up the oyster liquor, and you get a richness that's beyond what sausage or a little chicken broth can offer. As for the origins of oyster stuffing... it's complicated.
My mom is 91 years old now, but through the years, when I was a kid, the best thing about Thanksgiving was the stuffing. Hers was the best I ever ate. Loaded with flavor and completely delicious. When I got married and started my own family, I made sure I had this recipe in my recipe box. I've used it all my life.
