I am training for a half marathon.  At the start of my training I wasn't taking cherry juice.  As I increased my long runs each week my knees and hips were so sore.  I started to take this cherry concentrate and ever since then I have felt pretty good.  I take the juice every morning with my breakfast.  It has a very strong flavor but mixes well with apple or orange juice.  The half marathon I'm running in is this weekend and I feel ready for it thanks in part to the cherry juice helping reduce the pain.  This stuff works for me.

I don't know why this flour isn't available in grocery stores in the Midwest.  Typical grocer flours have a protein content much too high to give an authentic taste to such foods as pizza crust and homemade pastas.  And after years of making homemade pastas and trying to find that perfect recipe that would result in those served in the best Italian restaurants in the US and Europe, I'm happy to discover, the secret was in the 00 protein content all along.  What a fabulous difference this flour makes!  Freezes well too.
Positive

Opened a can that's not set to expire for another year and it was awful and rancid smelling. Rancid grains are toxic and it is terribly irresponsible of them to let this problem persist in food made for babies!! I won't buy their products again.
