Well, I tried it again and got the same result. Looks like Rose Levy Berenbaum is right (I hope none of you were placing bets). That means that either the pound cake in the Saveur photo is of a completely different cake, or a slightly smaller quantity of batter was baked in a 4-cup pan so it would crown well for the photo. Either way, they withheld the information the home baker (in this case, me) needed to recreate the cake in the picture. I hate that.
