In a skillet over medium heat, melt butter, then whisk in flour to form a smooth paste. Add half and half slowly, stirring constantly until thick and bubbly.
Whisk half of the that mixture into egg yolks then return all of the egg yolk mixture to the skillet. Combine well and stir in lobster meat. When lobster meat has heated through (about 2-3 minutes), stir in sherry and lemon juice.
Serve over puff pastry shells or white rice.
