Solomillo al whisky is a traditional dish originating from Seville. The dish consists of pork tenderloin in a garlicky whisky sauce and it's made with a combination of medallions of pork tenderloin, flour, lemon juice, garlic, whisky, olive oil, stock, and often potatoes.
The meat is browned, then removed from the pan so that the sauce can be prepared. When the sauce has reduced, the meat is added back to the pan until warm. It's recommeneded to serve solomillo al whisky with potatoes or bread to mop up the juices.
