Reading thru a little bit of this faq, I searched 'sauce' and found a few
sentences referring to 'sauce.' Some are interesting -- probably more refer
directly to a sauce a more elaborately prepared sauce. Interesting, but I
would not want to argue the true defintion of 'sauce.'
If a roasting pan has been used, cooking juices will have collected in
the bottom. They can be deglazed with a little liquid, such as wine or
water, to form a delicious gravy which can be poured over the roast or
served separately, or used to prepare a more elaborate sauce.
4.6 Braising
Braising is cooking 'by exchange', i.e. food (typically meat, but also
fish or vegetables) is first browned all over in a little fat (except
fish... see below), in a tightly sealed pot, immersed to half its depth
in liquid and cooked on top of the stove or in the oven, long, slowly,
and evenly, tenderizing it and, with the help of the juices that run
out, adding flavour to the resulting sauce.
KETCHUP - Also called catsup. Today, ketchup is mostly tomato-based
condiment or sauce .
