When it comes to buying yeast, I typically buy mine in bulk. And to be even more specific, I prefer buying the SAF Instant Yeast (for me, this yeast works like magic). After I have opened the vacuum sealed package, I then transfer the contents to a small canister with a tight lid that I keep in the refrigerator. I bake along happily using my yeast, until I come upon a recipe that calls for a "package" of yeast. At this point I am usually stumped trying to remember just how much yeast comes in a package; because you see I no longer have my original package from my bulk yeast which I'm sure gives the proper equivalents on the back of it. I always manage to find somewhere that 2 1/4 tsp. yeast is found in a small package. And no matter how many times this happens to me, I never can remember this particular measurement. But now, I have come across an actual "yeast measuring spoon". It measures precisely 2 1/4 tsp. This is really going to be nice!
