Melt butter is a skillet on medium-high heat. Once butter is melted, add salmon. Cook for 4 minutes on each side or until salmon reaches desired level of doneness. Remove salmon and set aside.
Add in garlic cloves and cook until softened. Stir in white wine and use to deglaze the pan and scape up anything that has stuck.
