Storing Fresh Cake Yeast

Toast

I just purchased a 1 lb. brick of fresh cake yeast to use in my bread baking and pizza making and was wondering if I could divide it up into smaller portions, vacuum seal it and freeze it?  

Everything I've read about fresh cake yeast is that it only lasts about two weeks in the fridge before it goes bad which is a shame. I hate to waste a pound that way. Your thoughts are appreciated. Thank you

You can cut off the desired quantity.  You need to use a bread knife because its very hard when frozen.  It will last a long time and in some cases even seems to have extra kick after frozen (yes it seems counter-intuitive)
