When I follow a recipe for a sauce it often talks about reducing by half (or whatever) to "thicken". But that *never* happens to me - it simply doesn't change in consistency at all until I have about only a tablespoon left in the pan.
For a while I'd just presumed it was me lazily using supermarket liquid stock (e.g. http://www.waitrose.com/shop/ProductView-10317-10001-13303-Waitrose+Cooks%27+ingredients+chicken+stock)
but I recently made my own chicken stock, and that is pretty much the same (made from a roast chicken carcass).
Is there just a missing assumption here that the stock to use is heavy in gelatin? Or what?
Why don't supermarket stocks like the above thicken? Same goes for their beef.
I can always use a cornstarch slurry, but I'd like to understand why my experience doesn't match up with any of these recipes...
Nice. Why can't the eggplant brown in the microwave? Mine did (halved the amount as serving for 2) but it didn't seem to harm the final result.
