Canning Blackberry Jam
22 Steps -- Step 15

Fill the Jars

We use a measuring cup to fill the jars with the Jam. We use a measuring cup with a handle that can hang on the inside of the pot. Fill the jar to a 1/4 inch headspace. Correct headspace is important in most all of canning. We use a towel to hold the hot jar while filling it. Bernice gets to partly fill the first jar so Paul can take a picture then he does the rest of the filling. He froze his hands in the Korean War so it is easier for him to hold hot items.
