Strawberry Jam

3 pints fresh strawberries
3 cups superfine sugar (yeah, it's a lot but sooo worth it)
2 tbsp orange juice
1/2 Granny Smith apple, peeled, cored and small-diced
1/2 cup fresh blueberries

Rinse and hull the strawberries then slice into quarters (leave smaller berries whole). Place the strawberries in a large heavy bottom pot and toss them with the sugar and orange juice. Bring the mixture to a boil over medium heat then add the apple and blueberries. Keep boiling and occasionally stirring for 25-30 minutes (until candy thermometer reaches 220 degrees). Skim off any foam that rises to the top. Allow to cool to room temperature then store covered in the refrigerator for up to two weeks. Serve with sliced and toasted baguettes or in a PB&J sandwich!
