Getting menu in order for St. Patrick's Day I plan on making a homemade
irish stew - using mutton- following directions in cookbook bought over
from Ireland with my friend's grandfather.

Recipe calls for homemade lamb broth which I have never made and don't
want to spend money buying a premade base that will go to waste using
once.

Been on Google but not really finding what I need.
Would any one in group like to share their favorite recipe for this and
also I plan on freezing any extra broth & wondering how long is the
freezer life of broths & stocks.

Thank You
