another simple trick…add in a couple slices of plain ol american cheese. Agreed on lots of butter and cream though too.
Edit: pass on the bacon. I like bacon just fine; but I am seriously over and sick to death of the “PUT BACON ON/IN EVERYTHING TO MAKE IT BETTER” campaign. Adding bacon to everything generally just makes those things taste like bacon. Again…I like bacon, but I want my burger to taste like a burger…not bacon.
