This is a recipe by Tyler Florence...........
I made it for Thanksgiving and it was such a hit! Its definetely a keeper.
I messed up.....the recipe called for 2 sticks of unsalted butter.....one was to be added to the potato and bananas and the other to the topping.
What I did was mucked up and added the full 2 sticks to the potato & bananas......oh and I used margarine (Imperial) vs. the unsalted butter.
I think the extra margarine was absolutely perfect and i have no plans to eliminate the extra next time......
Next time I plan on making 2 dishes of this as it went over so well and went so quickly.
