nice, thick rib eye, 1 to 1 1/2 inches thick, big enough for two

2 teaspoons
dark brown sugar
1 teaspoon
smoked paprika
1 tablespoon
coarse ground black pepper
1 teaspoon
ground cumin

chocolate stout (you'll have to drink the rest)

beef stock
1 tablespoon
unsalted butter
1 sprig
thyme
1 tablespoon
vegetable oil (if you are the type to save bacon fat, by all means use it!)
