Step 1

Line a baking sheet with waxed paper. In a large heavy-bottomed saucepan over low heat, combine sugar, brown sugar, butter, half-and-half, and pecans.

Step 2

Cook until sugar dissolves, about 2-3 minutes, stirring gently. Increase heat to medium and cover. Cook until sugar dissolves from the side of the pan, about 2-3 minutes longer.

Step 3

Uncover and cook until praline reaches soft ball stage, 235 degrees on a digital thermometer, while stirring constantly.

Step 4

Remove from heat. Using a wooden spoon, beat the mixture until it begins to thicken. Drop by rounded tablespoons onto the prepared baking sheet, and allow to stand at room temperature until firm.
