Keep trim frozen until you're ready to use it, then thaw the entire block. We recommend using it to make a bunch of game sausages at once. Once turned into bulk sausage or sausage links it can be refrozen.
For thawing instructions please read Safely Defrosting Food for Maximum Flavor.

Grind this trim thawed but cold using a meat grinder or attachment on your mixer. Mix with complimentary flavors of your choice and either use as sausage patties or pack the sausage into sausage casings to make links.
Flavors we recommend for pheasant sausage making include apples, juniper berries, bacon, onions, oranges, wine and truffles.
