Arrowroot is a good replacement. I get mine at www.penzeys.com
One Tablespoon of cornstarch per cup of milk.
Starch, also known as corn flour, is the active ingredient in cornstarch. This is a product you can use as a thickener in many recipes.
If you're baking, cornstarch is mainly a thickener, so you could try adding other thickeners: depending on what you're making, you could try potato starch, tapioca starch, etc.
Cream is not a good replacement for cornstarch. Instead use 2 tablespoons of flour for 1 tablespoon of cornstarch. Or you could use 4 teaspoons of quick cooking tapioca for 1 tablespoon of cornstarch.
Yes. I have had problems when trying to use old corn starch as a thickener.
For baked custard, no starch is used. The egg thickens it. For packaged custard mix such as Birds Custard, the thickener is cornflour or cornstarch and there is no egg.
no because cornstarch is sweet and flour is sour. I believe you use about half the amount of cornstarch when subsituting for flour.
1 Tablespoon Cornstarch = 2 Tablespoons flour
If your recipe calls for cornstarch but you do not have any on hand, you can easily use flour. If the recipe calls for 1 tbsp. of cornstarch, use 2 tbsp. of all-purpose flour.
No, cornstarch is a different product all together than corn flour. Corn flour is called Cornmeal in the U.S.
Your question is a little vague. Are you using the flour as a thickening agent? If so just dissolve 4-5 teaspoons of cornstarch into cold water and add it slowly to your sauce, stiring constantly until you get the desired thickness. You can always dissolve more into cold water and add as needed. Corn starch is much more effective thickener than flour, so usually much less is needed.
All-purpose flour can be used as a substitute for cornstarch.
