- Cook the Steak and Corn
- Heat a griddle pan over high heat until smoking.
- Remove the corn and steak from the marinade, pat dry, and drizzle with the remaining olive oil.
- Sear the steaks for 1–2 minutes per side until charred but still rare inside. Set aside to rest for 5 minutes.
- Add the corn to the pan and cook until charred. Remove and use a sharp knife to slice the kernels from the cob. Set aside.
- Prepare the Taco Shop Guac
