There are three blogs in Tajikistan that are a must read for anyone interested in Tajik cuisine.

Tajik Restaurant [Tarabkhonai Tojiki] [tj] shares cook-it-yourself videos and recipes of popular Tajik dishes. Suhailo's Cooking Diary [Daftari pukhtu-pazhoi Suhailo] [tj] teaches its readers to bake pastries popular in the country. Finally, Osh Khona [ru] offers detailed reviews of the best places to eat plov in Tajikistan. 

There is also the Tajikistan Cuisine [Taomhoi millii Tojikiston] [ru] public page on VKontakte, where hundreds of users share yummy recipes, pictures, and videos.

Warning: when you access these sources, be prepared to see much, much meat as Tajik cuisine is not for vegetarians.
