I have just subjected the SF Bay sewer system fishies to instant diabetes. I bought a couple of items today for some interesting cocktails and took a peek in the bottom shelf cabinet where some cordials and related spirits have been hiding for years. I opened them all, smelled and tasted most, spit out everything I tasted, and sent the remainder of the contents down the drain. These were:

Triple Sec - age unknown, barely any discernible flavo(u)r - maybe a hint of orange left.
Creme de Cacao - age unknown, barely a hint that some chocolate once lived in there.
Campari Cordial - I think I had it when I moved here, 19 years ago. Some thickened syrup went down the drain.
Creme de Banana - maybe the least disgusting of the bunch, and perhaps the newest. I do recall purchasing it for some recipe once upon a time, maybe a cooked fruit dessert.
Apple Pucker - it had a caramel (not green) colo(u)r and an odd smell. Someone must have once come over and made green appletinis or something.
Peach schnapps - ok, maybe the really least disgusting, and do not recall who brought it and left it here. Or maybe I flambeed it with something. Anyway, it now swims with fishes, if the sewer rats and flies don't consume it before the wastewater treatment plant.

These have been replaced with the following, for two interesting cocktail recipes:
1) Allspice dram
2) Creme de Cacao (Drillaud brand)

My house now weighs less, and will weigh even less than that when 6 glass bottles go out to the street next Thursday. Two of the bottles had actual price tags on them, one was $3.99.
