1. Make the Whiskey-Glazed Mushrooms:

1. In a skillet over medium heat, melt 1 tbsp butter.

2. Add mushrooms and sauté until golden and reduced, ~6-8 minutes.

3. Stir in garlic and cook for 1 minute.

4. Add whiskey (carefully), let it bubble and reduce slightly.

5. Stir in brown sugar and soy sauce. Simmer until thick and glossy.

6. Season with salt & pepper to taste. Set aside.

2. Make the Garlic Butter Drizzle:

1. In a small saucepan, melt butter over low heat.

3. Smash Burger Time:

1. Heat a cast-iron skillet or griddle over high heat until smoking hot.

2. Form ground beef into loose 2-oz balls (2 per burger).

🧄🔥 Chef’s Tips

• Don’t skip the smash: That crust from pressing the patty hard into the pan is key to flavor.

• Use a splatter guard: Smash burgers sizzle wildly.

• Whiskey note: Let the alcohol cook off for at least 30 seconds to 1 minute after adding.
