Everybody has their favorite nugget sauce. I usually go for BBQ sauce, although if the mood strikes, nothing hits the spot like sweet n' sour sauce. My other half goes for straight-up ketchup 100% of the time, and she's a nugget aficionado.
But there's reason to believe that the powers that be at McDonald's might favor honey, and it's pretty compelling. If nothing else, they are definitely pro-bee.
