1. Line a baking sheet with parchment paper or lightly grease it and set aside. Toast the pecans in a dry skillet over medium heat for about 5 minutes until fragrant, stirring frequently. This step deepens their flavor and adds a wonderful crunch.
2. In a heavy-bottomed saucepan, combine the granulated sugar, brown sugar, milk, and salt. Stir the mixture gently to combine without splashing the sides of the pan.
3. Bring the mixture to a boil over medium heat, stirring constantly. Use a candy thermometer to monitor the temperature—it should reach 238°F (the soft-ball stage). This usually takes about 10-15 minutes. Patience here is key; rushing can lead to grainy pralines.
4. Remove the saucepan from heat. Add the butter pieces and vanilla extract, stirring vigorously until the mixture thickens and begins to lose its gloss, about 3-4 minutes. This is when the magic happens—transforming the syrup into a creamy, spreadable batter.
5. Quickly fold in the toasted pecans until evenly coated.
6. Using two spoons or a small cookie scoop, drop spoonfuls of the mixture onto the prepared baking sheet. Work fast, as the pralines will start to set quickly.
7. Allow the pralines to cool at room temperature for at least 30 minutes until firm. Resist the urge to move them too soon—they’ll be sticky and fragile until fully set.

From my early kitchen misadventures, I learned that timing and temperature are everything with candy. Don’t be discouraged if your first batch doesn’t come out perfect—each attempt teaches you a bit more about how the sugar behaves. And if you feel like your pralines are too soft or too hard, adjusting the cooking time by a minute or two can make all the difference.
