Samanu (Persian: سمنو / samanu; Azerbaijani: səməni halvası), Samanak (Persian: سمنک / samanak), Sümelek (Kazakh: сүмелек / Turkmen: Sümelek / Syumelek), Sumanak (Tajik: суманак), Sumalak (Uzbek: sumalak [sʉmælˈæk]) or Sümölök (Kyrgyz: сүмөлөк [symœlˈœk]) is a sweet paste made from germinated wheat (young wheatgrass) and wheat flour, which is prepared especially for Nowruz (beginning of spring) in a large pot (like a kazan).

Traditionally, the final cooking would take from evening until the daylight and was a party involving only women.

They sit in a circle, sing songs, and have fun, each of them waiting for their turn to stir the sumalak.

Nowadays, it is common to add a bit of flour to speed up the thickening process, although this makes the paste taste somewhat bitter and less sweet.

In Iran, cooking and selling Samanu in the last days of the year has become a kind of seasonal trade, referred to the city of Ashtian, which is produced, sold and exported to European, Arab and East Asian countries.
