Customize It Your Way!

  • More Tang? Increase the vinegar for a sharper bite.

Why This Recipe Works (Perfect for Beginners!)

The quick soak keeps the potatoes from turning sticky, and the mix of vinegar, soy sauce, and a touch of sugar brings a perfect balance of flavors—sweet, sour, salty, and just a bit of heat. Plus, it’s so quick and forgiving that anyone can master it!

What to Serve with Stir-Fried Shredded Potato

This dish is fantastic on its own, but here are a few pairing ideas:
