In a small saucepan, combine sugar and vanilla sugar. Stir in the water and heat over medium. Cook, whisking occasionally, until all sugar is dissolved, about 10 minutes. Whisk in the rosewater.
Place almond meal in a medium bowl. Use a wooden spoon to stir in syrup. Once dough has come together, knead on work surface lightly dusted with almond meal until smooth.
Divide the dough into 3 equal pieces. To one piece, knead in red food coloring. Knead in green to another piece. Leave the third piece plain.
Roll each piece into a 3/4 inch wide rope. Place the ropes side by side and braid together. Push the braid together to seal and cut into about 1 inch long pieces. Roll each piece into a ball.
On a plate, sprinkle some superfine sugar. Roll each ball in the sugar and place on serving plate. Sprinkle with pine nuts, if using, and serve.
