In a food processor, combine the cranberries, jalapeño, green onions, lemon juice, sugar, and salt. Pulse until everything is finely chopped.
Place a mesh sieve over a small bowl and pour the cranberry mixture into it. Allow the juice to drain and reserve it.
In a mixing bowl, add the softened cream cheese and sour cream. Using a hand mixer (or stand mixer), beat until the mixture is light and fluffy, which should take about 2 minutes.
Add 1 tablespoon of the reserved cranberry juice to the cream cheese mixture and mix well. Then, gently stir in ⅓ to ½ of the chopped cranberry mixture.
Spoon the creamy dip into your favorite serving dish. Top with the remaining chopped cranberry mixture and garnish with a little extra green onion, a slice of jalapeño, or fresh parsley if you like. Serve this delightful dip with crackers, pita chips, or fresh veggies like celery and broccoli florets.
