Purée mixture in a food processor until smooth, then transfer pâté to crock and smooth top.
Melt remaining 1/4 cup butter in a very small saucepan over low heat, then remove pan from heat and let butter stand 3 minutes. If using herb garnish, put sprig on top of pâté. Skim froth from butter, then spoon enough clarified butter over pâté to cover its surface, leaving milky solids in bottom of pan. Chill pâté until butter is firm, about 30 minutes, then cover with plastic wrap and chill at least 2 hours more.
