What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Drain tuna thoroughly and press with a fork to remove excess liquid — this prevents a watery salad.
- 2Pat water chestnuts dry with paper towels after chopping so they stay crunchy and don't dilute the dressing.
- 3Fold the salad gently with a rubber spatula to keep the tuna flakes intact and the chestnuts crisp.
- 4Chill the finished salad for at least 15 minutes (ideally an hour) to let the flavors meld and deepen.
- 5Taste the dressing before mixing — adjust sriracha, lime, or salt to your preferred spice and tang level.
- 6Store leftovers in an airtight container in the fridge for up to 2 days; the water chestnuts may soften slightly.
