Murrī

What murrī was

Murrī was the salt-and-umami seasoning of the medieval Arabic kitchen. The medieval cookbooks use it in small amounts in almost every substantial dish, and it is named in the tenth-century Kitab al-Tabikh attributed to Ibn Sayyar al-Warraq. The finished product was a dark, liquid seasoning made from fermented barley, not from soybeans.

Modern writers have compared murrī with soy sauce because both are dark, salty and brewed from grain or beans. The comparison helps a reader place the flavour, but it does not describe the same material or process. The Aramco World article on the medieval Arabic cookbooks notes that murrī was never made from beans and was always a liquid. It was not borrowed from China.

How the medieval method worked

The method yields a fermented barley mass, not a sauce made in one step. In the North African method, barley is ground and mixed with water into a dough, which is wrapped in fresh fig leaves. The leaves help a mould develop. The dough is dried slowly over many weeks until it hardens into budhaj, the starter used for the next step.

Budhaj is then ground, mixed with water, salt and often more flour, and left to ferment again. Pressing the resulting paste yields the dark liquid. The Iraqi-style version given in later Arabic cookery books wets a mix of ground flatbread, barley flour and salt and lets it ferment, so the bread and the grain both feed the fermentation.

The sources do not identify which organisms do the work. Mould growth on the barley is documented in the descriptions; the roles of bacteria, yeasts and enzymes are not established by the sources read. Breakdown of starch and protein is the plausible route to the savoury taste, but the sources do not measure it, so it is not claimed here.

Why the ingredients matter

Barley is the substance of the process. The flour supplies starch and protein for the moulds and the second fermentation. Fig leaves were the medium used to encourage mould on the dough in the North African method, and the sources treat them as part of the method rather than as flavouring. Salt slows unwanted growth and shapes the flavour of the finished liquid. Flatbread, used in the Iraqi-style version, adds starch and some bread flavour.

The historical sources do not record exact weights. A reader should not infer a fixed ratio of barley to salt from this record.

Variations

Two families of method appear in the sources. The Iraqi-style murrī, given in the tenth-century Kitab al-Tabikh and the thirteenth-century Kitab Wasf al-Atima al-Mutada, uses ground flatbread, barley flour and salt. The Maghrebi style described in Kitab Wasf uses barley flour alone and flavours it with carob, fennel stems, citron, pine nuts, mixed spices and bitter orange wood, according to the Wikipedia summary of those texts.

Other medieval murrī recipes are not fish-based. Barley and must versions are documented as separate records in the research programme and are not merged here.

How it was eaten

Murrī was a background seasoning. The Aramco World article says most murrī-flavoured dishes in the book are vinegary, with one exception: a sweet, honey-glazed lamb recipe from the al-Barmaki manuscript. Murrī also seasons a fried eggplant dish with pepper and caraway, which the article calls the most unexpected flavouring in the book.

Because it was used in small quantities, it was closer to a salt or a sour-savoury note than to a sauce poured at the table.

Reading the record

The sources conflict on timing. One gives about forty days for each stage. Another gives a month or more. A third gives four months in total. The variation is itself the finding: the medieval texts did not standardise the method in a way that survives. Whatever the reader makes of these figures, they describe a historical process that ran for weeks to months under conditions the texts do not control.

The attribution also needs care. A 13th-century Kitab al-Tabikh by Muhammad bin Hasan al-Baghdadi is a different book with the same title, and murrī recipes appear in it. Quantities should be checked against a translation of Ibn Sayyar's text before anyone relies on them.
