Example Input: I discovered these when I moved to Canada a few years back.  Before this I had only experienced a thicker Wasa crispbread and was a bit put off at first.  The feelings dissolved the first time I ate one of these with light laughing cow cheese.  They are a little more "powdery" than I'd like, but they compliment most cheeses very well without overwhelming them.
Example Output: 4

Example Input: I bought a new bread machine and bought this collection of bread mixes as well as some single mixes to try it out.  The single mixes worked well as they included yeast packaged separately in the mix.  My machine states clearly not to get the yeast wet, to put it on top of the flour away from the water.  The mixes in this collection have the yeast in the flour, not packaged separately.  The bread failed to rise at all.  Why would they package the yeast separately in the single mixes and not in the multi packs?  Along with the Heartland Collection I also purchased the Baker's Choice Collection.  I am throwing them all out.  Don't waste your money.
Example Output: 1
