Combine ingredients: In a small bowl, mix the mayonnaise, mustard, barbecue sauce, honey, and the juice of the lemon and/or vinegar if used.
Mix well: Mix everything together with a whisk or spoon until it is smooth and creamy.
Taste and adjust: It should taste sweet with a subtle tang, but adjust to your satisfaction by adding a dash more honey or lemon juice if needed.
Serve and enjoy: Move the Chick-fil-A Sauce to a bowl or other container for serving. Enjoy immediately with your favourite foods, or transfer to a sealed container and refrigerate for up to 1 week.
