I've actually never eaten mutton, and I find lamb to be somewhat disgusting though in a different way than Lays brand Chicken and Waffles potato chips. It's not so much the combination of these vaguely compatible flavors -- after all, chicken sausage and waffles make for a fine breakfast -- it's the accumulated aftertaste. I liken it to the taste-equivalent of the odor of unprocessed sheep's wool. That cloying, lanolin-drenched smell of fresh-sheared herd mammal. Why this is I have no idea. Possibly it's a case of two chemically similar flavones (flavonoids? I may be making this stuff up...)
In any case, offer these to players you don't intend on having back to your table.
