I purchased a bottle of Italian Glace by Colavita. Since then I have purchased several bottles of balsamic vinegar and cooked it down to make my own. I have never seen it called Glace again so I've been using the term Glaze. I've, also, discovered that by dripping it around a plate for presentation with four half slices of lemon on each corner. As the lemon picks up the glace the sweetness of it and the sour of the lemon are a perfect compliment !! And it looks great ! While I've been unable to discover why they use the term Glace .... guess I'll just email the company !
