It's been a week since I first cut into it and it's now as good as that first slice -- it may even be better. With time the rye gets a full flavor, almost spicy, and the sourdough element keeps its tang.
On a very different note, the ultimate winter comfort lunch:
It's a grilled cheese of cheddar and sourdough semolina bread (this and the last from Hamelman's Bread) with an cream of tomato soup from Deborah Madison's Vegetarian Cooking for Everyone. It leaves me with just a few jars of tomatoes from last year's canning madness, but was well worth it.
