Preheat oven to 350 F (180 C). In a large bowl mix olive oil, garlic
and parsley. Heat the beef
broth until steamy then add to the olive oil mixture. Mix in barley flour
and let cool until
lukewarm. Gradually mix in rye flour, adding enough to form a stiff dough.
Transfer to a
floured surface and knead until smooth, about 4 min. Shape the dough into
a ball and roll
out to 1/4 inch thickness. Using knives or cookie cutters cut out the
biscuits. Transfer to
a cookie sheet spacing them about 1/4 inch apart. Bake for 30 min. Turn
biscuits over and
bake for 30 more minutes. Let biscuits cool overnight.
