I found a spoon at the thrift store that looks like it might work out ok, for twenty-five cents, it's low risk. Stainless steel, not silver or silver plate, though. Only able to find one so far.
Saw a pack of six soup spoons at a dollar store but they looked like they'd been stamped out in China with ridges on the edges, not something I want to put in my mouth.
