So just go ahead and put this in your own words, hope this helped :)
Step-by-step explanation:
To thicken sauces, cornflour is combined with cold water first, which is called a slurry. Flour, on the other hand, is cooked with fat and made into a roux. If you use cornflour in your recipes and you try to swap with flour you will need more of it to get the same effect. In general, it's recommended that you use twice as much flour as cornflour for thickening purposes. So if you need 1 tablespoon of cornstarch, use 2 tablespoons of white flour.
