I always mix my cornflour (thickening agent), with a little water till its a thick paste and then blend it in. The other night on one of the many cooking programmes i watch a lady said she was thickening with with cornflour and she seemed to be just pourning a white fluid from a jug, it seemed much smoother and lighter (i think thats the best description). would this work?
It was the same thing you were doing but with more water. Generally, when thickening with corn flour/corn starch, you mix water and the flour to make a slurry, a watery suspension of flour in water. Then you stir up the mixture and pour into the pot to thicken.
