To bring things up a notch, I purchased brioche rolls, Tillamook cheddar, cremini mushrooms and onions. Hours earlier Heather talked me through the process, she having lived in the land of 10,000 lakes knew something about this regional phenomenon.When dinner rolled around I caramelized some sliced onions, then sauteed some cremini with leeks, and thyme. I split the soft brioche rolls and made the cheese stuffed patties. The grill pan heated. The burgers sizzled.
Topped with onions and mushrooms the stage was set. Juicy, meltingly satisfying... those Minnesotans had something there. The only thing that would have made it better would have been an iced cold pop.
