Taking an extra long break from baking is not the best idea. I tried baking a loaf after a 2½ month long break, and it was the same as me having never baked before. Add to it the fact that I used a fresh batch of flour, and I ended up with the driest loaf I have baked thus far. It had reasonably good flavor, but got almost no rise.
I should try getting a new batch of instant yeast. I don’t know why, but my yeast never froths the way they show on TV.
