I noticed that cook's illustrated lists two types of "cobbler" recipes--batter style and cookie dough style. One where you melt butter in a pan and put batter on top, with the fruits on top of that (batter style). The other type involves putting the fruit first, often heating it in the oven, and then layering the batter on top (cookie dough style). The latter also uses eggs and a higher butter to flour ratio)
Which one do you prefer? Batter at the bottom or on top?
