Eight oranges peeled to the pulp, blended with water and sweetened with honey rather than sugar. No juicer needed, and straining is optional.
This is blended, not squeezed, which is the Colombian way and why the recipe says no juicer is needed. It also means the pith has to come off properly: the white layer under the rind is bitter, and a squeezer never touches it while a blender turns it into the whole drink. Take the seeds out too, for the same reason. The water is optional. The recipe's own note says you can add as much or as little as you like, or none, and the difference is real: eight oranges blended on their own give something thick and intense, and two cups of water turns it into a long drink. Honey rather than sugar is what this recipe uses. It dissolves into cold liquid more easily than granulated sugar does and it brings its own flavour, which sits well against orange. Straining is a matter of taste. Left unstrained the juice has body and settles into layers; strained it is smoother and thinner.
