Keto-friendly honey mustard!
Mix equal parts high-fat mayo, dijon/deli mustard, and sugar-free honey. This makes a great honey mustard for a dip or glaze.
Note that for the sugar-free honey, you may be able to find it locally. My local Wal-Mart had it for only $2 or so, not the $17 extortion on Amazon.
