What makes this hack taste like an In-N-Out Double-Double?
The combination of grilled onions, peppers, and cherry relish creates the sweet-savory-tangy profile similar to In-N-Out's signature sauce and toppings on a double burger.
Can I substitute the chipotle mayo?
Yes. Regular mayo mixed with a pinch of smoked paprika and cayenne, or any chipotle-flavored spread, works as a substitute.
