Strawberry refrigerator jam

I bought a few quarts of strawberries on the way home from the shore last weekend.  I cleaned up one quart for a friend in recovery from surgery, and used another to make a quick batch of strawberry jam.  It's 'refrigerator' jam insofar as it's not processed after cooking for long-term storage at room temperature.  This is jam you make and eat.

1 qt ripe strawberries (And apologies, I didn't weigh them.  This is one quart dry measure.)
2 cups sugar
pinch salt
juice of half a lemon

Hull the berries, and halve or slice them, depending on how large they are, and place in a pot -- at least a 4-qt pot -- you need the extra room.  Add the sugar, salt, and lemon juice.

Bring to a boil over high heat, and stir.  As the water in the fruit begins to boil off, the jam mixture will start to bubble up.  You know you've achieved a high enough temperature when your stirring does not knock down the bubbles.  Be very careful not to let it boil over, removing it from the heat and stirring vigorously as necessary. 

Continue to cook the mixture for about 20 minutes until it thickens, and reaches a temperature of 220°F, at which point it's done.

Pour into a clean jar (I used a clean 1-quart mason jar), cover, and let sit at room temperature until it is cool.  You'll see that it sets up nicely when it comes to room temperature.  Tighten the lid, and pop into the fridge.

I really cannot adequately describe how remarkable the taste of homemade strawberry jam is.  Words fail.

By the way, the best resource for jam- and jelly-making is the National Center for Home Food Preservation, based at the University of Georgia.

And on a cracker with some butter.
