Tips for the Best Spicy Tuna Salad Jars

For the best flavor, let the tuna mixture chill for at least 30 minutes before layering — this allows the heat and acidity to meld. Always use airtight glass jars to maintain freshness.

For a creamier consistency, increase the yogurt slightly, and for extra spice, add a pinch of crushed red pepper or more Sriracha.
