I was going to suggest pouring butter over the bread but I can see that many others have already done that! I love a basic recipe but using a fall beer, like Leinenkugel’s Oktoberfest to give it a better flavor. But definitely try a recipe with butter all over it while baking. That gives you the super crispy crust! A basic version: http://glitterandgoulash.com/quick-beer-bread/
Using lemon-lime soda is very interesting!
