Is it possible to make a dorodango out of flour?

Many materials which are tightly compacted (with water, white glue, etc) can be polished after hardening so perhaps various kinds of "air-dry clay" like those made with flour** could also be polished to create a shiny surface (don't know if just water would hold flour balls together well enough for the polishing, but maybe).

The air-dry clay shapes might need to be very even though to be nicely spherical, or they'd have to be sanded/carved/etc first to create a rounder shape, then polished.

Not all ingredients in air-dry clays or other materials might be fine-grain enough though to polish evenly and completely.

The usual way that air-dry clays are given a shiny surface is coating them with a clear gloss finish (polyurethane, fingernail polish, some kinds of floor polish, permanent white glue diluted with water or aka "decoupage medium" like ModPodge, gloss acrylic mediums for acrylic paints, epoxy resin, etc).

Or some may become shiny if just compressed hard enough onto a *very* smooth surface before drying (like in a very smooth mold).

Real rocks, etc, are compacted hard enough that they can be polished in a rock tumbler with other teeny rocks, grits or various kinds of powders, that get smaller and smaller for greater and greater shine (or in the running water/grit/silt of a river stream for almost-glossy finish).

(And btw, *polymer clay* --which is not an air-dry clay-- is often wet-sanded then polished with something electric to create a highly glossy surface, though sometimes clayers just add a clear gloss finish, or bake them in direct contact with a very smooth surface or in a smooth mold. Or hardened polymer clay can be polished in a rock tumbler like real rocks, though not with the usual hard grits used for rocks since polymer clay is much softer. Polymer clay is basically plastic though so can be made shiny in various ways just like other plastic objects.)
