Which kinds of rice can replace Uzbek devsira?
Surely this will make your Plov unauthentic, but in practice any medium-grained rice will be an acceptable substitute. If you find the correct spices (or close enough; cumin gives most of the flavour anyway), and some nice fat lamb, you should be able to make a delicious dish.
Even if the article on TripAdvisor mentions fermented and aged rice, this is a rarity; in most cases ordinary non-aged rice is used.
