Freeze butter for a few hours prior to making this recipe.
Mix together water and lemon juice in a small bowl and set aside.
In a large bowl mix together flour and salt. Grate (just like grating cheese) frozen butter. I used a grater with large holes. A cheese peeler also works nicely. Mix butter into the dry mixture. I used my hands to really blend everything together.
Slowly add in the water and lemon mixture, taking care to add a little at a time. I found I did not need it all using the "Paleo flour". The desired dough will be soft and pliable but not "wet". Wrap the dough in saran wrap and chill in the refrigerator until use.
