What to keep in mind.
5 tips from the recipe — small details that make a real difference to the final dish.
- 1Pat the lettuce leaves completely dry after washing; any moisture will make the cups soggy and dilute the tuna salad.
- 2For the best texture, drain the canned tuna very well and flake it with a fork into small, even pieces before mixing.
- 3Chill the mixing bowl and ingredients for 10 minutes before assembling to keep the lettuce cups cold and crisp longer.
- 4Mix the tuna salad gently—over-stirring will make the filling pasty instead of pleasantly chunky.
- 5Make the tuna salad filling up to 24 hours ahead and refrigerate; fill the lettuce cups just before serving to maintain crunch.
