In a non-stick skillet or cast iron pan melt butter in a skillet and sear the salmon on both sides for 3 minutes.

Lower the flame to medium and add the broth to the skillet. Scrape the bottom of the pan with a whisk to incorporate the salmon bits into the sauce.
Continue to cook the sauce until it reduces to 1/3 of the original amount. Remove the sauce from the heat and whisk in the butter and yogurt.
