amber, just chop the dill, about a tsp of dill per coupla tbsps of unmelted butter, and just mix together with a fork or whisk.
i like to add a little basil as well.
i put little chunks of the dill/basil butter on top of the salmon, skin side down, and put it under the broiler. when it is done, ad put just a little more to melt on the hot fish.
it's not a sauce per se, but it's really good and the salmon stays moist, and gets a nice browning/crust from the butter.
hope this helps.
