I have cooked mutton in this house exactly once. Never again. It took multiple days, wax melts, open windows and a box fan to get the goddamn stink out, and I can only imagine how much worse goat is, since goats are just the trashcan version of sheep from the world's armpits and asscrack.
To be fair though, I've heard that mutton from one part of the world will taste like a completely different animal than one from another region. I'm still not willing to risk that incredible stench again, though. For those of you who are able and knowledgeable enough to source mutton or goat that doesn't smell and taste like Allah is punishing us, you have my envy.
