Measure the glutinous rice flour into a bowl. Add the milk one tablespoon at a time, stirring after each addition. Try not to add too much milk so the dough doesn't get too sticky to shape.

Knead the dough until smooth. Divide into portions and add food coloring as desired.

Shape the dough into small balls or any shapes you like. Sprinkle a little flour on them to prevent sticking.

Boil water in a pot. Drop the shaped dough into the boiling water and cook until they float to the surface. Remove and place them in a bowl of plain water.

For the sauce, mix the whole milk with sweetened condensed milk. Warm it slightly in the microwave or over low heat on the stove. Pour the warm milk sauce over the cooked dumplings.
