Mosto cotto is a syrupy reduction of balsamic vinegar. If you can’t find Saba, or another ‘mosto cotto’, use ⅓ cup balsamic vinegar and 1 teaspoon sugar.
When you buy Portabella mushrooms, look for caps that are dry, with undersides that are velvety and a light taupe in color. They should have a light mushroomy scent. If you see any black wet patches on the undersides, or the mushrooms smell dank or sour, they are old.
