Sauces and condiments from Iraq, North Africa and al-Andalus

Murri (medieval barley "rotted" condiment)مري (murrī)

Murri was a dark, salty liquid seasoning of the medieval Arab world, made from barley dough that was left to rot (budhaj) and then fermented with salt and water in the summer sun. It has been compared with soy sauce for its savoury taste. It was used widely in cooking and died out after about the 14th century.

Recipe

Amounts from a sourceAl-Baghdadi's recipe, as quoted on David Friedman's page with Charles Perry's correction of "penny-royal" to budhaj, uses 5 ratls each of budhaj and flour. Friedman gives a 13th-century Andalusian ratl as 468.75 g; other places used other ratls.

At a glance

Murri was a dark, salty liquid seasoning of the medieval Arab world, made from barley dough that was left to rot (budhaj) and then fermented with salt and water in the summer sun. It has been compared with soy sauce for its savoury taste. It was used widely in cooking and died out after about the 14th century. Made in 4 steps over 2.6 months. The longest step, make budhaj (rotted barley), takes 40 days (An Anonymous Andalusian Cookbook of the 13th…). Salt is 33 % (An Anonymous Andalusian Cookbook of the 13th…). Mould that grows on the unsalted barley dough does most of the fermenting.

What makes this one different

Unlike soy sauce, murri was made from barley, not soybeans. Its mould starter (budhaj) was grown by leaving unsalted barley dough to rot in a closed container, and the salted paste was then fermented in an open trough in the summer sun.

Variants

  • Iraqi style (Kitab al-Tabikh, al-Warraq, 10th c.)Ground flatbread plus barley flour plus salt, wetted and fermented.
  • Maghrebi style (Kitab Wasf al-At'ima al-Mu'tada, 13th c.)Barley flour only, flavoured with carob, citron and other ingredients.
  • Byzantine murri (made "right away")Not fermented. Scorched honey, scorched bread, starch, spices, carob, walnuts, quinces, salt and water are boiled until a third of the water is absorbed and strained.
  • Kamakh (murri plus milk)Murri mixed with milk was known as kamakh, according to Wikipedia. The atlas has a separate entry for kamakh rijal.

Safety

This page records a medieval method. It is not a tested recipe, so do not make budhaj at home. Budhaj is unsalted barley dough left to rot for about 40 days, with no salt or leaven in it, and no source we read names the mould that grows. Moulds on damp grain can make mycotoxins, which WHO says range from acute poisoning to cancer and mostly survive food processing [who-mycotoxins], so the later salt, sun and straining cannot be relied on to remove them. No period source gives salt as a percentage, and no modern study has measured a reconstruction, so nothing shows it holds back harmful bacteria either.

History and sources

Every number is labelled with how it is known. How this atlas is made

Charles Perry calls murri a kind of soy sauce made by culturing barley dough. Its terms mix Persian (budhaj, "rotted"), Aramaic (qamn, "mould") and Greek (murri, from halmyris, "something salty"), so he concludes it must have arisen in the Fertile Crescent. He finds no evidence of murri in Iran or Byzantium, but says it was popular throughout the Arab world in the Middle Ages, with recipes in Arabic cookery books of the 10th and 13th centuries; Iraq and North Africa had their own versions and knew each other's. Friedman writes that it vanished sometime after the fourteenth century. The "Byzantine murri" of the 13th-century Kitab Wasf is apparently a fake substitute made by a simpler process.
