Measure fruits into a large bowl. Measure sugar and set aside. Combine Certo fruit pectin crystals with 1/4 cup of the measured sugar. Gradually add to fruit, stirring well. Let stand for 30 minutes, stirring occasionally. Gradually stir in remaining sugar and continue stirring for 3 minutes until most of the sugar is dissolved. Pour into clean jars or plastic containers. Cover tightly with lids. Let stand at room temperature until set (may take up to 24 hours). Store in freezer or up to 3 weeks in fridge. Makes 6 cups.
