I love sauce and thick sauce, nothing worse than a watery sauce. Have ever wondered how to thicken a sauce when you find that it is too thin? There is an easy way to thicken it. All you need is some cornflour (also known as sauce flour) and water. Combine about a heaped teaspoon of cornflour and mix it with enough water to make a thinnish paste. Add a couple of tablespoons of your hot sauce and mix. Now pour it all back into your sauce mix well and let it cook through for a minute or so. If you find it still not thick enough just mix a little more cornflour. Conversely, if it is too thick you can add a little water.
