Pralines

Line a baking sheet with aluminum foil.

In large saucepan over medium heat, combine pecans, sugar, butter, brown sugar, milk and vanilla.

Heat to between 234 and 240 degrees F (112 to 116 degrees C), or until a small amount of syrup dropped into cold water forms a soft ball that flattens when removed from the water and placed on a flat surface.

Drop by spoonfuls onto prepared baking sheet.

Let cool completely.
