When to use a Recipe
The short answer is always. You will be able to tinker with recipes once you get comfortable with time and temperature as well as what ingredients are strictly needed, but if you are just starting, be sure to stick with a tested recipe. Also, if you are trying to can something for the first time, it is suggested that you use a recipe in order to make sure the ingredients reach the proper temperature and pressure to be safe in the can.
How To Use A Recipe
Using a recipe is as easy as reading a book. Just like baking is a matter of exact measurements, canning is also an exact science of food making. It is important to make sure canned foods are safe, and the only way to do that with some types of food are to follow the directions for the recipe exactly. Keeping the foods in the canner at the right temperature and time ensure the lack of bacteria and the less chance for the food spoiling.
Be sure to look at all of the ingredients needed before you start the canning process because the last thing you want to do is have to run to the store because you forgot something while you are trying to can.
Canning is a lot of fun and a great way to store your hard work for a later time. Recipes are there to make the process easier and to take some of the guesswork out of how to bottle your goodness safely and with a lot of flavor. If you are just starting out or trying something new, stick with the recipe on the first go-round because the last thing you would want is a spoiled jar of hard work.
