Add 1 cup sugar and 1 tablespoon water to a saucepan over medium heat. Stir often until melted and just turns an amber in color, making sure it doesn't burn and stick to the bottom of the pan. Remove from heat.
In another saucepan, heat milk over low-medium heat until steaming with bubbles around the edges.
Slowly whisk the milk into the caramelized sugar.
Add remaining sugar and stir.
Cook on medium-low heat until a soft thick ball begins to form - and a candy thermometer reads 240°F.
Remove from heat. Stir in butter, orange zest, and pecans.
Beat until creamy and slightly cooled.
Drop by tablespoons onto wax paper and allow to cool for 30 minutes.
