At the suggestion of Cheebs on the Chocolate Alchemy forum, I got a couple of these and cut the tips to about 1/4":
They work really well for a controlled pour. I would also pour with the mold on a scale.
Clever suggestion. I currently use squeeze bottles. How do you get leftover chocolate out of the syringe?
There's not much chocolate left in the syringe--just a tiny bit in the nozzle. I just clean it with hot water or put it in the dishwasher.
