1. In a saucepan, combine sugar and 1 cup water and bring to a boil over high heat, stirring to begin dissolving sugar. Reduce heat to medium and simmer, stirring occasionally, until sugar has dissolved completely, 5 minutes. Add tangerines and continue to simmer 8 to 10 minutes, until fruit is translucent and syrup has thickened. Remove from heat, set aside, and let cool.

2. In a blender, combine flour, egg, yolk, melted butter, and milk, and blend until smooth. Cover and refrigerate at least 1 hour and up to overnight.

3. Place an 8-inch skillet over medium-high heat, add a knob of butter, and swirl pan to coat bottom evenly. Ladle 1/4 cup of crepe batter into hot pan and swirl pan to coat bottom evenly with batter. Cook until batter is lightly browned on bottom, about 1 minute. Using a small metal spatula, lift edge of crepe and flip it over. Cook other side until golden brown.

4. Transfer to a warmed plate and repeat with remaining batter. To serve, fold 2 crepes in half, place them on a plate, and spoon some candied tangerines on top.
