Pour the 480 ml fresh heavy cream into a clean glass jar or bowl.
Add 2 tablespoons of fresh whole milk to the cream and stir gently to combine.
Add 2 tablespoons of fresh lemon juice to the mixture and stir well.
Cover the jar or bowl loosely with a clean kitchen towel or plastic wrap, allowing some air to circulate.
Let the mixture sit at room temperature (about 21-24°C / 70-75°F) for 24 hours, or until it thickens and develops a tangy flavor.
Once thickened, stir the sour cream gently, then cover tightly and refrigerate for at least 4 hours before using.
Store homemade sour cream in the refrigerator and use within 1 week.
