Dice the tomatoes, onions and green pepper. Place in a large canning kettle and sprinkle with the coarse salt. Stir the mixture a little. Cover and let stand overnight. Drain the accumulated liquid and place the mixture back into the canning kettle. Add the vinegar and spices to the mixture and boil gently until the desired thickness is achieved. This will probably take four hours if you want it thick. I boiled withthe lid on for a couple of hours before I reduced the volume. Once the desired thickness is achieved turn off the heat and stir in the brown sugar until dissolved. Place in sterilized 500 ml bottles and seal as you would if you making pickles. Store in a dark cool place. The sauce does improve with age. This recipe yields 12 500 ml bottles.
