Strawberry Jalapeno Jam - cooking recipe

Ingredients

4 cups crushed strawberries (discard stems and leaves)
1 cup jalapeno pepper (processed in food processer)
1/4 cup lemon juice
1 (1 3/4 ounce) package powdered fruit pectin (Sure-Jell Premium yellow box I prefer using 1 1/2 packages if strawberries are runnier)
7 cups granulated sugar (yes this is the right amount...it's jelly!)

Preparation

Sterilize eight half pint canning jars with lids and rings, boiling for at least 5 minutes and kept hot.
Place the crushed strawberries (do not chop in a food processer; the texture will be too fine and choppy), processed jalapeno pepper, lemon juice and pectin into a large, heavy-bottomed saucepan; stir in the sugar to dissolve. Rapidly bring to a boil over high heat (long, slow boiling destroys the pectin). Once at a full rolling boil, cook for 1 full minute. One half teaspoon butter may be added to keep down the foam, if desired. Letting this mixture sit for about 5 minutes discourages the fruit from separating.
Pack the jam into the hot, sterilized jars, filling the jars to within 1/4 inch of the top. Run a knife or a thin spatula around the insides of the jars after they have been filled to remove any air bubbles. Wipe the rims of the jars with a moist paper towel to remove any food residue. Top with lids and screw on rings.
Process 10 minutes in a boiling water canner. Remove the jars and place onto a cloth-covered or heat-resistance surface. (While cooling, I shake frequently to redistribute content.) Allow to cool overnight. Store in a cool, dark area.
