Saffron, truffles, and caviar, good bets. Some other possibilities:
Serbian donkeycheese: $600/lb (though I doubt they carry it at Kroger’s supermarket)
Kobe/Wagyu beef: at least $100/lb, regardless of pedigree.
Good vanilla extract: ~$20/8 oz. or same for a half dozen vanilla beans.
Canned pate or the like: No cite here, but fois gras is absurd, $60/lb or so, and even shitty pork liver pate by Roland can be upwards of $20/lb. I splurge every couple months for duck confit, and it’s about $30/lb. It’s my baby boy’s absolute favorite food, so I justify it.
At least I get to share. I’d make it myself, I know how, but buying duck or goose itself is ridiculously extravagant in the Midwest. Which is weird, because there are rampant geese shitting everywhere. I should get a dart gun or something and start poaching…
Charcuterie: horrendously expensive in the U.S. Good salami, prosciutto, bastarma (highly-seasoned pastrami), bresaola, speck, even humble fatty beef bacon or lardo/slanina…all upwards of $15/lb. Stupid. These are the remnants of butchery, given a salt/smoke cure or some such because they’re no good otherwise, commanding gourmet prices due to rarity. But they’re mostly nice treatments of the byproducts of butchery and shouldn’t be any more pricy than bologna or souse loaf.
Tuna: Not talking about Starkist. To get little canned fillets of Italian tuna, you’ve got to pay about $10 per 6 oz. jar, and that’s if you’re looking hard. Fresh, at a sushi joint? Don’t get me started. I don’t even know how to codify their pricing, especially for otoro. If you want it, you just better be ignoring any prices, not that you’ll be informed ahead of time.
Speaking of which…oysters. Near their port of origin, quite cheap, maybe $.50 per. Anywhere else, expect $3.50 per, even though they were removed from the sea 2 days prior. :rolleyes: Oysters are not *that *good, y’all, and I bet you put hot sauce or something on them.
I will not comment now on non-nutritious comestibles like various brandies and port.
