One was we didn&#8217;t have a working oven; another was a low-carb diet I was on. However, with both those obstacles cleared, I got back to baking bread last Thursday. I don&#8217;t know when the last of it got eaten, but there&#8217;s none left, so I guess it turned out all right.<\/p>\n<p>\nI really like baking bread, and have written numerous posts about it (see <a href=\"https:\/\/www.oracletutoring.ca\/blog\/lifestyle-do-you-have-to-proof-yeast\/\">my post from Nov 25, 2017<\/a>, for instance). Yet, like any habit one leaves for awhile, it might take a bit of extra concentration to restart.<\/p>\n<p>\nOne situation that confronted me immediately last Thursday was the yeast: it had two different &#8220;use by&#8221; dates at different places on the jar. One said a date in 2019, the other, a date in 2022. Either way, it seemed to be way overdue. Moreover, it said on the jar something to the effect of &#8220;Use within six months.&#8221;<\/p>\n<p>\nWhen one bakes all the time, and keeps using the same container of yeast, one might not care about such things; the yeast worked last week, so one expects it will this time. Intuitively, one might not expect yeast can lose function in just a week.<\/p>\n<p>\nYet, three or six years on, might yeast lose its activity? Not likely, I thought, so decided to proof it.<\/p>\n<p>\nAs it turned out, the yeast proofed fine; subsequently, the dough raised as it should have, and so on.<\/p>\n<p>\nHow yeast could have two use-by dates on it, three years apart, might be one mystery. Perhaps the whole situation is academic. However, the bread was real.<\/p>\nJack of <a href=\"https:\/\/www.oracletutoring.ca\">Oracle Tutoring by Jack and Diane,<\/a> Campbell River, BC.\n","protected":false},"excerpt":{"rendered":"<p>Self-tutoring about baking: the tutor mentions using &#8220;old&#8221; yeast to make bread.
