Most of your sense of taste actually comes from your nose, so the snorting menthol is probably the most likely to work. Eating a steady diet of constant foods won't really kill any taste buds, it will just dull the flavors of less extreme foods. I would think you'd need to keep eating the spices, though, as this doesn't seem like a permanent solution. Something you might want to try is holding your nose while you eat; this won't totally kill your sense of taste, but it might dull it a little bit.

Personally, though, I think tasting good food is worth at least a grand a year.
