This unique burger delivers a massive punch of bright, acidic flavor. The secret is a homemade batch of whole pickled lemons that cure for weeks to soften their rinds and deepen their tang. These intensely sour citrus slices sit right on top of a savory, pan-seared beef patty. A quick garlic and lemon sauce ties the whole sandwich together. It is a bold, unforgettable meal for anyone who loves serious citrus notes.
