In a large mixing bowl, combine the mayonnaise, sugar, lemon juice, white vinegar, salt, and pepper. Whisk together until everything is smooth and well-mixed.
Add the coleslaw mix to the prepared dressing. Use a spatula or large spoon to stir until the mix is thoroughly coated with the dressing.
Place the coleslaw in the refrigerator for at least 2 hours to allow the flavors to meld together.
Notes
For extra tang, consider adding a splash more vinegar.
Use fresh lemon juice for the best flavor.
Mix in additional mayonnaise if coleslaw seems too dry after refrigeration.
Add a pinch of cayenne pepper for subtle heat.
Diced apples or dried cranberries can add a fruity twist.
