I used one of those packets of active dry yeast. The directions for the bread maker called for active dry yeast (no proofing mentioned) so I figured it didn't rise because the yeast had an "best by" date of Nov 09. Guess I haven't done much baking in a while. Do you recommend always proofing first even for a bread machine? I don't really want to use the "instant" bread machine yeast. I suppose I should make real bread in an oven. I suck at baking.
