Quantity
Make sure you have enough of each item to be canned. This way you can make it through the winter. A little prior planning can go a long way and can really make the difference in the winter dishes. Imagine having freshly canned green beans in your casserole during the holidays, instead of having to use poor quality ones found in the grocery stores during that time.
Pick and can more of the items you know you and your family will use, after all, they can be used at a later date and it is better to have more than less. The canned goods can also be used to give away as presents or special gifts to those who are dear to your heart.
