For all my yeast baking, I always use bread machine yeast. I also always use my bread machine for mixing and kneading of the dough whether I bake in the oven or in the machine, even if the recipe says to use a mixer. When putting the ingredients into the machine pan, I put the liquids in first which include the sugar and salt, then the gluten-free flour mix and finally I put the yeast on top of the flour not touching the liquids. When using milk powder, that also goes on top on the edge not touching the yeast.
When using the bread machine yeast, usually I only have to raise the bread or buns covered in a warm place for about 15 minutes. While baking the bread or buns, they will rise even more while cooking.
