In a separate medium saucepan over medium-high heat, mix granulated sugar, brown sugar, cream, butter, and baking soda. Attach a candy thermometer and cook, stirring constantly, until the mixture reaches 113°C. Remove from heat immediately.

Stir in the chopped pecans, vanilla extract, and salt. Allow the mixture to cool for 3–4 minutes, then stir until it begins to thicken and loses its sheen.

Let the fudge cool completely at room temperature for at least 1 hour. Once firm, lift it from the pan using the parchment paper and cut into squares.
