Mayo burns at a higher temperature than butter and much cheaper.  Mayo allows your seasonings to stick to the meats while grilling and allows for a
beautiful, caramelized crust to develop on the meat.   
 
While working on the road I use BBQ grills to cook most of my dinner meals.  I've been asked more than once at the hotel's grill why I'm slathering
mayo on my seasoned steaks/burgers.  The answer is how perfect the outcome is without a hint of observable mayo. Plus, it keeps the meat from sticking
to the grill.  Only problems are flareups if you leave the meat unattended.  |
