Sriracha Dipping Sauce with sweet potato fries

I remember how delighted I was when I discovered Sweet Potato Fries, and the recipes for Air Fryer Sweet Potato Fries and Spicy Baked Sweet Potato Fries both are favorites of mine. And even though the sweet potato fries are tossed in a mixture of spices, I absolutely love this Sriracha Dipping Sauce to go with my sweet potato fries. I’ll sometimes even eat this sauce on (gasp) frozen sweet potato fries like the ones in these photos, although there’s no doubt that from-scratch sweet potato fries are better.

This sauce is the perfect dip for sweet potato fries, and in my niece Kara’s family her teenagers make this over and over, even when she isn’t home. Fresh lime juice is the secret ingredient that I think makes this over-the-top good! And if you don’t want the carbs from the sweet potatoes fries, keep reading for ways to enjoy this sauce for a low-carb treat!
