Currently, the price of fresh morel mushrooms.
Perhaps, ResQDoc, if you went out and gathered a pound of morels, you wouldn't feel quite the same way. Expensive? You betcha! But they're not something you can cultivate in your backyard, either. It takes time, energy, and expense to gather them.
also, not getting what you pay for, like extracts that are so diluted they don't even come close to the flavor.
Joey, while I agree with your concept, and certainly object as you do, the problem lies with food legislation. Take a look at how these (and other food) products are defined by law. F'rinstance, "pure vanilla" can contain vanilla extracts, alcohol, and sugar (usually, nowadays, in the form of hfcs). So what you often get is, in effect, a vanilla cocktail, with the vanilla playing a minor role.
Ever looked at the definition of "vine ripened" tomatoes? It explains why you and I don't eat fresh tomatoes most of the year.
It's precisely because people---including professional cooks and chefs---don't understand the legal aspects of food marketing that manufacturers get away with such dilutions. If Brand X says pure vanilla, and sells for $3.00/ounce, and Brand Y also says pure vanilla, but sells for $7.50, most people will gravitate to the one selling for three bucks. When it barely tastes like vanilla, though, they should be calling their congressman, not the manufacturer.
