As a thickner for stew, or pies, you can use self rising flour.
Another good option is to use arrowroot powder.
For making gravy, a good substitute for corn starch is enriched white wheat flour. You can also substitute gluten-free flour. You might also try tapioca flour. You can also substitute potato starch, but use the commercial kind. If you make your own liquid starch from juiced potatoes, be ready for that potato taste... and, it tends to turn very slightly grey.
can i use corn flour instead of corn starch to remove stain from leather boots
No...
Although corn flour and corn starch derive from the same part of the plant, they are NOT the same thing, and in cooking, they behave very differently. If you use corn starch to make tortillas, you'll get an inedible glob of goo. On the other hand, if you use corn flour in place of corn starch, you'll get gruel instead of gravy or sauce or pudding. Corn flour and corn starch should not be confused with (or used in place of) corn meal, which, although related, is a totally different product with a totally different purpose.
No you cannot constarch is for u to use for ur icing
Flour and corn starch are measured the same, but the results aren't always the same.
Then it wont come out good.
Corn Starch
No, it won't work. potato starch is just shredded potato, so the potato would just dissapear in the water and the water would be sticky.
No. the only thing these two have in comon is the colour.
No, just use regular clothing starch, or hairspray works well too.
Yes. I have had problems when trying to use old corn starch as a thickener.
Baking soda is not at all similar to tapioca starch, so you would get a very different result if you replaced one with the other. A more logical substitution for tapioca starch would be corn starch.
