What goes in the bag
One-quarter cup of concentrated veal demi-glace.
Prepare & package
Keep the concentrated demi-glace in a measured freezer-safe package. The physical count and earlier conversation indicate a prepared product, but the brand and exact production date are not confirmed.
Store & thaw
Keep frozen in the sealed measured package. Thaw in the refrigerator or loosen gently over low heat.
Cook or reheat
Add in small amounts to pan sauces, braises, gravies, or reductions. Heat gently and dilute only as required by the final dish.
Finish & serve
Taste the final sauce before adding salt; demi-glace is concentrated.
