Combine graham crackers, sugar, salt, and melted butter in a mixing bowl.
Press the graham cracker mixture into the bottom of a buttered 8-inch springform pan.
Place the crust into the freezer for 20 minutes.
Meanwhile, with a hand mixer or stand mixer, cream together the cream cheese, heavy cream, powdered sugar, vanilla, lemon juice, and zest in a large mixing bowl.
Fold the chopped cranberries into the cream cheese mixture.
Pour the cheesecake filling into the springform pan and spread evenly.
Wrap the cheesecake in plastic wrap and set in the freezer for 12 hours.
Make the sugared cranberries by heating 1 cup of water with 1/2 cup of sugar.
When the water starts to simmer, add the cranberries and stir.
Remove the pan from the heat and let the cranberries sit for 5 minutes.
Use a slotted spoon to remove the cranberries onto parchment paper.
Then roll the cranberries into more sugar.
Set on parchment to dry.
Move the cheesecake to the refrigerator an hour before serving and garnish with sugared cranberries if desired.
