Combine beef, worcestershire sauce, pepper and season with salt. Form 4 patties; thinner in the center.

Heat a cast iron skillet over med-high heat. Cook burgers turning once till desired doneness. Transfer to a plate. I like to warm a plate first then cover so they stay warm.

Add stock to skillet and cook stirring until slightly reduced.
