Place the pecan halves in a sauté pan over medium heat and toast until fragrant, stirring occasionally.
Line a muffin tin with parchment paper liners. Arrange half of the toasted pecans into small clusters inside the liners, reserving the rest.
Combine half of the Kraft caramels with 1 tablespoon of half-and-half in a microwave-safe glass bowl. Microwave at 50% power in 30-second intervals, stirring frequently, until smooth and creamy.
Spoon the melted caramel over each pecan cluster, making sure it touches all the pecans and holds them together.
Melt half of the chocolate melting wafers in a microwave-safe bowl at 50% power in 30-second intervals, stirring after each interval until smooth.
Spoon the melted chocolate over the caramel-covered pecans, allowing it to spread and drip gently over the caramel.
Sprinkle a small amount of kosher salt over each candy while the chocolate is still melted.
Refrigerate until the caramel and chocolate are completely set.
Repeat with the remaining pecans, caramels, half-and-half, and chocolate to make 24 turtles in total.
Remove from the refrigerator once fully set and serve at room temperature for the best texture.
