Well - the coffee roasting experiment seemed to work out well. Took about 1/3 cup of the beans and put them in an aluminum pie plate one layer deep. Roasted them under the broiler for about two-three minutes on each side.
The roasted beans were only slightly darker than the original ones, but they were much oilier. Also, though the flavor of the coffee was milder than the Trader Joe's stuff, I noted that two cups of it didn't wasn't making me dizzy like the past couple days. Also, the kitchen smelled heavenly.
I might try roasting the stuff longer tomorrow morning; we'll see. Am glad, though, to have found a workaround, even though it is a bit of a pain in the rear. We have like a pound and a half of the city roast left, and it was getting to be painful to drink.
