I've seen a device before that can be filled with any liquid and it would allow you to control the amount of liquid being dispensed, say, hot soup into shot glasses. I want to buy one, but I don't even have a clue as to what it's called. It looks just like a china cap, but solid instead of perforated. There's also a lever on the handle that controls the opening and closing of the valve on the tip of the cone. If anyone could help me out with what this thing is and possibly websites to buy from, I'd be greatly thankful.
