A system for pouring liquids from a vessel is provided with a mounting flange that engages an inner surface of a vessel sidewall and a spout that extends from the mounting flange. A biasing member depends from the spout to engage an outer surface of the vessel sidewall and securely engage the mounting flange with the inner surface of the vessel sidewall. Guide walls may extend up from the mounting flange on either side of the spout. A separator plate may be removably secured with the mounting flange to strain solids from the liquid being poured from the vessel. The spout, alone or in combination with the separator plate, may form a utensil support.
