We all like the convenience of great-tasting “one jar meals”. But, any additions or deletions made to an approved canning recipe would need a new process time calculated for it. It is not safe to change the recipe and use the same process time for canning. One-dish meals often include thickening ingredients or are cooked down to a thicker consistency than expected for the process time for an individual ingredient. These situations are likely to result in hazardous foods. You may add your special ingredients after you open up a safely canned jar of food, to make a dish. Also keep in mind that after canning and storage, your special recipe may no longer taste exactly the same as when it is made fresh. Sometimes special recipes are best enjoyed as freshly made dishes.
