Do yourself a favor and invest in a good mother-of-pearl spoon. Why? The pricey little utensils are a must-have if you plan to savor even the least costly caviar. See, when a place serves you an ounce of the finest beluga or osetra roe with a dainty silver spoon, the easy-to-tarnish metal may impart a tinny flavor to your fancy eggs. But not mother-of-pearl. Now, with the proper tool in hand, you're ready to decide whether you want to drop $63.83 for a half-ounce of olive-black Kaluga Fusion Gold or an eye-popping $140 for the same amount of Russian Reserve osetra. If caviar isn't your guilty pleasure, Marky's Gourmet has every other stripe of sinful indulgence. Want a whole duck foie gras from Hudson Valley Farms? Yours for $148.78. A pound of dried French morel mushrooms? That'll be $266.50. Perhaps you're less flashy and like to cloak your refinement. For that, just go for one of Marky's fine cultured French butters. They're only about $20 a pound.
