The corned beef. I cooked two pieces together, one from each bucket. They had to overlap in the pot when I started.
The results so far- the piece from the first bucket was pinking up nicely along the edges, and you could almost tell where I had poked it, as the pink followed through in spots. It mostly tasted like corned beef, although it was a little heavy on the pepper. The piece from the second bucket remained a grey colour, right through cooking, and tasted more like very peppery roast beef than corned beef.
So, the rest shall remain in the basement a few more days, awaiting another taste test.
