Fill the blender with 3/4 ice. Add sweet & sour mix to the top of the ice. Add about 1 of pineapple juice, 1/2 of melon liqeur, and 1/2 to 1/4 of amaretto. Then blend the mix until it is of margaritta consistency or thinner.

This is made in a blender, hence the measurements are according to a blender.
