Those silicone scrapers always advertise that they are inert and impart no taste to the food. I have found this to be untrue-- even after a trip in our heavy-duty German dishwasher. One lick. Yuk.
I have a small plastic scraper about 2 inches square that seems to be inert, but it is quite stiff and has no handle, so it's pretty useless most of the time. Any suggestions?
The scraper you are referring to is used when washing the pot or pan. Taste is not an issue at that point, since you are cleaning everything and would not normally have any reason to use it other than in soap and water. You should use this instead of steel wool or other abrasive cleaning tools. I keep mine in the drain basket at all times, and wash it in the dishwasher.
As for the spatula, my biggest complaint is that silicon and rubber tend to attract dust and hair, so I make sure that I rinse each piece off before using it, even though it has been lying in a drawer with other clean utensils.
I have no idea why you would worry about this thing imparting taste. Wooden spoons are far more porous. Just wash them well in hot soapy water, and stop licking them for heaven's sake :) There couldn't be enough "taste" in them after washing well to affect anything unless you have a piece of junk on your hands.
Don't worry about the taste you experience when you lick the spatula. If you need to taste your food as you're cooking (as you should), use a separate teaspoon or tablespoon. What you're tasting is the spatula. I've noticed this same thing with wooden utensils, silicon, rubbermaid plastic spatulas, etc.--the taste of food off those implements is really gross. But they do not impart any off tastes to the food itself. (Exception may be if you have a really old or ill-washed wooden utensil, they do get rancid if not cared for properly and should be discarded.)
