Can I use pre-ground beef instead of grinding chuck steak myself?
Yes, but freshly ground chuck steak delivers superior texture and flavor. If using pre-ground, choose 80/20 beef chuck from the butcher counter for best results.
What makes the special sauce different from regular mayo?
This sauce combines pasteurized egg, avocado oil, apple cider vinegar, mustard, garlic, shallot, and tomato paste for a tangy, savory depth that plain mayo lacks.
Why is the smash technique important?
Smashing the patty flat creates more surface area for browning, develops a crispy crust, and allows better cheese melting than a thick burger would.
Can I make the special sauce ahead of time?
Yes, store it in an airtight container in the refrigerator for up to 5 days. The flavors actually improve slightly as they meld.
What type of cheese works best for this burger?
The recipe calls for 8 slices of cheese for two double burgers. American, cheddar, or Swiss all melt well; layer them while the patties are still hot.
