These muffins are really moist and really lemony. This is my oldest son's favorite muffin. The recipe come's from an old copy of Bon Appetite. My Dad always likes to add a few lemons into packages he sends us from California, which always makes these muffins extra special. 9-16-09 Since this was first posted it has become very difficult to find yogurt in the 8oz size so you either have to buy 2 6oz yogurts or add a little extra plain yogurt or a little sour cream. This is a very firm dough, not a loose batter like most muffins, but the muffins still come out nice and moist, enjoy!
