Heat butter in a non stick pan or skillet over medium-high heat. Melt, swirling pan and stirring occasionally for about 3 minutes, or until the foam settles; the butter begins to change in colour to golden brown and has a nutty fragrance.
Add the honey, lime juice, soy sauce, garlic and chili flakes; stir well to combine all of the flavours together and cook for 30 seconds until the garlic is fragrant.
Remove from heat. Pour out just over half of the browned butter from the pan (liquid only), leaving 2 tablespoons of the lime butter mixture in the pan, and reserve the rest for later.
Add half of the shrimp to the lime/butter in the pan, season with salt and pepper. Sear for about 2 minutes each side, or until just cooked through and no longer opaque. Transfer to a plate, set aside.
Wipe pan over with paper towel and add 2 more tablespoons of the lime/butter mixture to the pan. (You may need to add 1 teaspoon of olive oil or extra butter to the pan if your sauce has thickened too much.)
Season and sear the remaining shrimp for 2 minutes each side, or until just cooked through and no longer opaque.
Add the cooked shrimp back into the pan, and pour in the remaining lime/butter sauce; stirring through the shrimp to evenly coat. Season with salt if desired and garnish with parsley and extra chili flakes (if desired).
Serve with steamed vegetables; over rice or with a salad
