You know the drill about getting started on the water bath canning. Placing a rack in the bottom of a pot in order to keep the jars up to a high position of the bottom of the pan. It allows creating space for water to be around the jars as it prevents the rattling between the jars.
Then, adding water as long as it covers the jars at least one inch higher of the lids. After that, fill the jars according to your recipe. After that, close off the tops and rings following the alignment.
Now, turn up the heat, count the timing according to the recipe of yours. In general, the canning process is done in 10 minutes. The truth is it depends on the heat and the jars’ size, e.g., if the jars are 4-12 ounces, 10-12 minutes of heating would be enough, and if the jars are 16 ounces, then 15-18 minutes heating would be enough. It will take more than 20 minutes if the heat is not delivered correctly.
Wait for the water to be fully boiled up, only then will you turn off the heat and let the jars cool down. Usually, it takes 5-10 minutes. Later on these processes, you know the next procedures.
