If you do not have tomato stew, the process to making one is easy. Simply blend some tomatoes, red bell peppers, onions and some habaneros(ata-rodo). Heat up some oil, chop in some onions, sauté and pour in the tomatoes. Season and cook until the tomatoes has reduced and the oil has floated to the top.
You may use baking soda to help with viscosity. Just mix ¼ tsp with a little water and stir into the soup
