This is so easy. And once you make it, you’ll kick yourself for not having made it sooner.
2 cups mashed strawberries
4 cup sugar
1 package of powdered pectin (1-3/4 ounce)
1 cup water
Combine strawberries and sugar in a bowl. Allow to sit for 20 minutes or so, stirring occasionally.
Combine pectin and water in a saucepan, and bring to a boil. Boil for 1 minute, stirring constantly. Stir the pectin into the strawberry-sugar mixture, and continue stirring for 3 minutes.
Pour into wide-mouth freezer jars, leaving 1/2-inch head space. Adjust caps, and let stand until set, but no more than 24 hours. Freeze.
Makes about 5 half pints.
