<<Just curious as to what products are best used for thickening sauces,>> I like arrowroot as it takes such a little amount and it doesn't change the flavor say like flour or cornstarch and is quick. Rice flour's not bad either, it depends on the sauce. If you want to make a sauce creamy not really thick a whipped egg yolk is a nice thickener as well, but you must take some of the hot sauce into a bowl whisking the egg into the cooled portion then add back to the main sauce while whisking continuously so as not to curdle.
