In a large pan, 6-Quart works perfect, place clean and cut in half strawberries and then add Sure Jell Pectin and butter, which helps cut down on the frothing.
Bring the fruit to a boil over high heat making sure to stir constantly.
Add the measured sugar and stir well until you feel the sugar dissolved, then bring to a rolling boil for 1 minute stirring constantly.
Remove the pot from heat and then skim off any froth that has formed on the top, then ladle into sterilized pint jars with a canning funnel leaving 1/4-inch headspace.
Remove air bubbles from the jam by sliding a knife along the edges.
Wipe all of the rims clean with a clean and damp towel.
Place lids on jar and screw on bands until fingertip tight. Do not tighten the lids all the way!
Place jars in a canner rack and then carefully place rack into canner with simmering water. Make sure the water is 1 to 2-inches above the jar lids.
Bring to a boil and then process the Strawberry Jam jars for 10 minutes.
Remove the jars from the water using a jar lifter tongs and rest until cool on a towel or cooling rack.
After 24 hours, check lids to make sure they popped. If not, that jar can go right into the fridge. If sealed properly, store in a cool dry place, remember to additionally add a date and name on the jar so you know what is inside.
