Hot tips From Food Network Kitchens’ Katherine Alford:
Add a twist to sandwiches or tacos with custom mayonnaise: Mix plain mayo with citrus zest or juice, fresh herbs, chopped olives or a condiment like pesto or Sriracha. (We made chile-lime mayo for the tuna tostadas pictured above.) Keep the leftovers in the fridge, covered, for up to three days, but taste before reusing: The flavors can intensify after a day or two, so you may need to mellow it out with more mayo.
