They're there--you might need to relaunch your browser (to clear the cache), before they show up. The ingredients are now listed as follows, but there are additional changes, so do look at the whole recipe:
4 racks baby back pork ribs (6 to 8 pounds total)
2 cups firmly packed brown sugar
1/2 cup coarse salt (kosher or sea)
1/4 cup freshly ground black pepper
I made the ribs and I found them salty as well. Which taught me a simple lesson - taste the rub and sauce before you put it on. If you don't like it before it's cooked you probably won't like it after. Personally i don't like a lot of peppe so I put in about a teaspoon and it tasted better the next time.
