A while ago I wrote about how Schwartz herb and spices jars are rubbish, being actually designed in a way to make impossible to take the contents out of the jar by the most common method of measurement for herbs and spices – a teaspoon. Well I wrote them a letter asking why this is, and here’s their reply:

So apparently a metal spoon would somehow contaminate or get moisture the spices, where as holding it over a steaming pan of food will not. It all makes sense now.
