Kaster (كاستر, in Kurdish kestê) is a type of Iraqi milk dessert. It is one of the most widespread and popular desserts in the territory of present-day Iraq. It is a regional variant of pudding prepared from a powder mixture (custard powder), milk, and sugar, which is specific for the addition of local aromatic substances, especially cardamom and rose water. The dish is served chilled and is often combined with a layer of jelly or nuts on the surface.

The Name Is a Phonetic Transcription of the English Word “Custard” into Arabic. The spread of this dessert in Iraq is related to the British Mandate for Mesopotamia (1920–1932) and the subsequent British influence in the region. During this period, British foods entered the local market, including powdered pudding (custard powder), which was originally developed in Birmingham in 1837 by Alfred Bird as an egg substitute for people with allergies. In the hot Iraqi climate, where preserving fresh eggs and milk was difficult, the durable powder represented an ideal ingredient. Iraqis adapted the British base and enriched it with local ingredients.

Consumption of Kaster in Iraq Is Associated Primarily with the Period of Ramadan. Due to its consistency and sugar content, it is a frequent part of Iftar (the meal breaking the fast) or Suhur (the meal before the fast begins). The dessert is also commonly served at family gatherings and wedding receptions as one of the items on the sweet buffet. In Iraqi confectioneries and street stalls, it is sold in disposable plastic cups.
It was on the street that I tasted it myself; one substantial portion cost me 1,000 IQD (0.60 EUR).
Bon appétit!
