Yes, you can safely use the Granite Ware F0707-2 porcelain-enameled canner (319814) to make and can chili sauce. The porcelain enamel creates a non-reactive, glass-like surface that is perfect for acidic foods. Before using, inspect the interior carefully for any chips or cracks. If the enamel is damaged and exposes the steel core underneath, you should not use the pot for cooking.
