Recipe for vegan demi-glace
I love sauce and umami, and therefore I must admit that I don’t venture much into the vegan kitchen. Nevertheless, there’s so much curiosity in me that I often feel like trying to see if vegan versions can measure up to the “real” ones.
For the longest time, I’ve wanted to make this recipe, and when I finally took the time to do it, I must admit that it almost perfectly matches an ordinary demi-glace/red wine glaze.
Normally, it takes many hours to make a demi-glace, but this vegan version can be made in under 2 hours.
The recipe is relatively easy but does require Xanthan Gum and pectin, which are not readily available everywhere.
