Soak minced red onions in water for 15 minutes. This helps tone down the onion flavor, so it doesn’t overpower the other flavors.
Boil, peel, and cut potatoes into small pieces. Sprinkle the apple cider vinegar on top. Set aside to cool.
Boil the eggs. Cut into small pieces. Set aside to cool.
Chop the celery and dill into small pieces. Set aside.
Combine the sriracha, mustard, mayo, lime juice, and salt. Mix until well combined.
Now it’s time to put it all together! Add the potatoes, eggs, celery, onion, and dill into a large bowl. Drizzle the sriracha mayo on top. Mix until well incorporated.
Taste for flavour and add more salt if needed. Put it in the fridge for 30 minutes before serving. This helps all the flavours combine.
