Demi Glace

Store in an airtight container. Commercial canned or jarred demi-glace may have longer shelf lives before opening; check the packaging.

Demi-glace can be a bit salty, so taste before adding additional salt to your dish.

To thin it out, add a little water, stock, or wine.

Freeze in ice cube trays for easy, pre-portioned additions to sauces and stews.

Red meats like beef, lamb, and venison

Poultry, especially duck and roasted chicken

Root vegetables

Mashed potatoes

Grains like rice and polenta

Over-reducing the sauce, which can make it too thick or even bitter.

Not tasting and adjusting seasoning, potentially leading to an overly salty or bland final dish.
