Oh I know the recipe,

Ingredients : goat (bakra), aduwa, lasun, rato khursani, tel, pasupati ko goal (charcoal)

process: take a goat and cut it into 4 pieces. before cutting ask it if it wants to be killed vertically or horizontally. If you have religious restrictions u can do halal or kroser as well. after cutting goat. take one piece and grill it in charcoal fire. u can buy pasupati ko goal near pasupati 40 rs per tin (thats where all sekuwa near airport is made).

put in all the ingredients together and let it marinate for 30 mins. Mean while u can play taas , any game. your tash is ready to be eaten now. for better taste dont clean the goat after or before killing.

note: if you know a better recipe don't post it until u have a national consensus in it.
