Mushrooms I used tonight. Gently wash with water and pat them dry.

Fire up your demi glace and place it on low to simmer for about 2+ hours until it reduces by about 3/4. Or, until it can coat the back of a spoon. No need to stir this. Just make certain it's always simmering. Add 3 Sun Dried Tomatoes to this glace after simmer starts and remove it 1 hour into simmer. Notice by the pan lines just how far this glace has reduced. This means ALL the flavor is in that pot as you read and mushrooms can't wait to absorb it.

Chop your garlic, shallots and mushrooms in quarters and add to a frying pan with 2 tbs Olive Oil, a tablespoon of butter and a nice splash of your demi glace. Fry mushrooms and additions in that for about 2 minutes with lid to steam.

Pour all of your demi glace into your mushroom seasoned pan and bring it to a simmer. Add 1 tablespoon Corn Starch and a small splash of water to a small bowl and mix that very well. Add that corn starch thickener to your simmering demi glace and whisk quickly. It'll tighten up pretty fast. Check for any clumps and discard if any. Chances are, if you whisk this quick enough, you won't have any. Your glace won't be pretty at this point but she'll be delicious! When you can run a line thru your glace and see the bottom of your pan for a few seconds, she's done.

Spoon drizzle demi glace over your mushrooms but don't over do it. While you haven't added any salt yourself, this reduction can be a little bit salty.
