Add the
tomato paste to the saucepan and mix in with a wooden spatula. Add the
flour and mix. Deglaze the saucepan with the
wine used for the marinating. When well mixed, add the
tripe pieces, tomatoes, stock, and herbs. Bring to a boil, reduce to a low simmer, and
cook for about 4 hours until the
tripe is no longer chewy.
