अलि बोसो काम भयो होला. 100 % lean meat is not good for MoMo . Use about 10-12 % fat also. I use about 20%. That is excessive tara I like it that way. Also after wrapping don't keep it standing too long. and don't save unused wrappers for later. Try to use it all.. If not air-tight seal गरेर store गर्ने . If all else fails. MSG or अजीना - मोटो . Good Luck.
