I bought a jar of Fleischmann’s Instant Yeast in 2020 for my first foray into pretzel making. The “Best Before” date on the jar was September 2022, but I kept using it and the pretzels tasted just fine.
I ran out of that yeast today and bought a new jar; I guess the old yeast had gotten rather feeble, because the pretzels I made today rose at least an inch higher than the ones I’d made a few weeks ago (though you’ll have to take my word for it; I don’t photograph every batch of pretzels I make!).
It’s restful being home!
Old yeast, just like old men, not a whole lot of pop…
