Slice unpeeled tomatoes as for table use and put in a crock in layers. Sprinkle each layer with salt ending with salt. Place a light weight on them. Let stand 5 days and drain off the liquid each day. On the 6th day, drain very well and run through colander. Tie spices in a bag and put in pulp and cook for 45 minutes. Take cornstarch and water and make a smooth liquid and add to catsup and cook about 10 minutes. I add cornstarch enough till the right thickness. Note: the tomatoes will have a bad odor when putting them through the colander, but they are alright.
