trick about cake baking

hi willy 6, my dear itsa nice and an easy tip that you have shared with all of us but you not told the quantity of vinegar that has to be added in it . wont it gives a sour taste or something like that and if the quantity is not known then for bet , i will spil my cake, i am very bad in it. i can make only when i know the exact quantity of the things that has to be added to my cake. i have baked cake but all studied welll their proportiions and all that. otherwise i will spoil them. i am not an expert in it. i have baked cookies and of various flavours, major wheat mixed with flavours and all dry fruits also sometimes . i love to bake.

how much vinegar should you mix with the bakin soda?? does this work only for cakes or like will work with muffins etc?? i love to bake but am still a newbie...
