the substitute is called cornflour. cornstach is just a diffrent name for cornflower
In food eggs
No, you shouldn't really substitute for eggs, but usually water and oil are used to substitue. (Not one or the other, a little of both)
Probably not. Baking mix has other ingredients such as baking soda/powder and dried milk or eggs. What type of baking mix is it and what are you making? If you're just battering something it will be fine, but if you're baking something, not so much.
No, salt cannot be substituted for baking soda in baking recipes. Baking soda is a leavening agent that helps baked goods rise, while salt is used for flavoring. Using salt instead of baking soda will result in a very different outcome in terms of texture and leavening.
I'm not positive. The reverse substitution is for 1 tsp. of baking powder, you use 1/4-1/2 tsp. of baking soda and 1/2 tsp. cream of tartar. So you could try using baking powder instead of cream of tartar, but it's not guaranteed. If there is supposed to be baking soda and cream of tartar in the recipe and you substituted baking powder, that would be more likely to succeed.
no
Nothing..
I suppose that is possible.
NO
No, eno and baking soda are not interchangeable. Baking soda is pure sodium bicarbonate, while eno is a combination of sodium bicarbonate, citric acid, and soda carbonate, and also contains flavoring agents. Substituting eno for baking soda may alter the taste and texture of your baked goods.
Transformation of coal in a substitue of oil.
Baking powder is a good alternative to baking soda. Yeast isn't recommended. You really can't subsitute it. After researching on the internet I have found that this is true, baking powder would be the only substitue.
