The genetics

Genotype En_ over a tort base. The shading of the tort interacts with the random patching of the broken gene, which is why the results are so variable.

What a good one looks like

A complete butterfly, coloured ears, and shading that still reads as tort within the coloured patches rather than as a flat brown.

What to check for

Loss of the tort shading within the patches, which leaves you with a broken fawn rather than a broken tort. Incomplete butterfly.

Is broken tort actually rare?

Uncommon as a well-marked example, common as a pattern. The combination of shading and patching means each one is genuinely unique, and that is the appeal.

Common questions

Why does every broken tort look different?

Because two random things are happening at once. The tort itself is shaded, and the broken gene patches colour over white at random. The interaction means no two broken torts look remotely alike, which is precisely the appeal.

What should I check on a broken tort?

That the tort shading still reads within the coloured patches rather than flattening into a plain brown. And a complete butterfly, as with any broken.
