Roman barley gruel (Puls)

Barley porridge of Roman gladiators and legions

Origin: Roman Empire

From the journey of Barley.

Puls was the foundational food of Rome, the thick porridge of cooked grain that fed the Roman legions, the urban poor, and (famously) the gladiators. Ancient writers called gladiators 'hordearii', barley-eaters, and modern isotopic analysis of gladiator bone fragments from a cemetery in Ephesus confirms they had a diet extremely high in barley and plant protein. The energy density, complex carbohydrates, and subcutaneous fat that barley promoted was understood empirically: well-padded muscles and body fat protected gladiators from the superficial slash wounds that constituted the primary spectacle. Roman legionaries carried barley as emergency rations (wheat puls was the preferred version, but barley was lighter and more storable). This recipe reconstructs the simplest military and gladiatorial version: barley, water, salt, and fat, with the optional additions of garum (fish sauce) and olive oil mentioned in Roman sources.

Ingredients

Main

  • 200 g pearl barley

Liquid

  • 900 ml water

Seasoning

  • 1 tsp salt
  • 1 tsp fish sauce (garum substitute, Thai or Vietnamese fish sauce)
  • 1 tbsp dried fenugreek seeds, ground (optional, documented Roman seasoning)

Fat

  • 2 tbsp olive oil (the Romans used a lot of it)

Method

  1. Rinse the barley. Place in a saucepan with the water and bring to a boil.
  2. Add the salt and fenugreek (if using). Reduce to a gentle simmer, cover, and cook for 35–40 minutes, stirring occasionally, until the barley is completely tender and the porridge is thick.
  3. Remove from heat. Stir in the olive oil and fish sauce. The fish sauce adds the crucial savoury depth that garum would have provided: do not omit it if going for historical accuracy.
  4. Taste and adjust salt (carefully: the fish sauce is salty). Serve in deep bowls.

Notes

This is food that asks nothing of you and asks nothing of the cook. It sustained armies. A Roman legionary could march 20 miles on it. The fish sauce makes it deeply savoury in a way that is unlike modern porridge: almost brothy. For the complete gladiator's meal, serve alongside a hard-boiled egg, a piece of salt-cured meat, and a cup of posca (water mixed with wine vinegar).
