This may be an odd question but I am wondering if you use a recipe that calls for yeast that is not instant yeast, I know there is always sugar or honey involved to activate the yeast. I also know that if you use instant yeast, which is what I use it doesn't need to be activated or mixed with water and sugar, so my question is: If the recipe calls for the sugar, can you omit it? If so, then you would just add the water to the liquid ingredients right? Or, do you still need the sugar in the recipe. Will omiting the sugar change the taste that much? Thanks!
