I was testing two packets of old expired yeast. I put each packet into its own bowl of water and dissolved them with some sugar, spilling some yeast out of the first packet. They both worked fine, so I used one of the bowls of dissolved yeast in my bread. What do I do with the other bowl of dissolved yeast and sugar? Can I just dump it down the drain? And secondly, my recipe makes two loaves of bread, but I only have one bread pan. The dough is supposed to rise twice, once before I shape it and again after I put it in the pans (if I had two pans). While half of the dough is going to be rising the second time in the pan, will the half without the pan rise okay on the cutting board?
