Harissa arbi

Tunisia, Cap Bon and Nabeul

Harissa arbi: A thick, coarse, deep brick red chilli paste heaped in a small glass jar, the surface levelled and sealed under a film of green olive oil. The texture is visibly rough rather than smooth.

Inscribed by UNESCO on the Representative List on 1 December 2022, as Tunisian. Read the inscription carefully, because press coverage embroiders it: the official text names no governorates and no pepper varieties, and specifies only salt, garlic and coriander as the seasonings. What it does describe is chillies sun-dried, split, destalked, deseeded, washed, ground in a mortar or a manual mincer, and stored in glass or pottery, prepared usually by women in a family or neighbourhood setting. Three grades are named and are not interchangeable: harissa berbère, more heavily spiced; harissa arbi or diari, the coarser household grade; and harissa m'dacha, mortar-ground and most rustic. Deseeding is not squeamishness. Capsaicin lives in the placental tissue that holds the seeds, so removing it turns a punishment condiment into one you can use by the tablespoon, and the warm soak that follows does not leach what heat remains, because capsaicin is oil-soluble. The garlic load, at 35 per cent of the chilli weight, is far higher than any Western recipe: it is the paste's sulphurous backbone.

As tradition built it

Makes about 500 ml. 1 hour, plus 30 minutes soaking.

Ingredients

Method

  1. Destalk, deseed and wash the chillies.
  2. Soak in warm water 30 minutes, then drain thoroughly. Wet chillies make a thin paste that will not keep.
  3. Grind the garlic and fennel to a smooth paste before anything else touches the mortar.
  4. Add the salt, then the chillies, then the caraway and coriander, and grind to a thick, coarse paste.
  5. Work in olive oil until it is glossy and holds its shape.
  6. Jar it, level the surface, pour a film of oil over the top, refrigerate. Re-oil after every use and never introduce a wet spoon: mould from a broken seal is how most good harissa dies in a British fridge.

Notes

The kilo ratio comes from two independent Tunisian sources in agreement; the table is that ratio at a quarter scale.

What a modern chef changes

Smoked chillies, seeds toasted to order, and a mortar rather than a blender

Rungs 2, 3 and 6

Method

  1. Smoke the chillies before you soak them. The restaurant step UNESCO does not describe, documented by Sam Lamiri: 48 hours over olive and eucalyptus wood, depositing guaiacol and syringol phenols that read as depth and cover the raw green note of any under-dried pepper. On a Big Green Egg, as cold as you can hold it, chillies far from the fire. Even four hours changes the paste.
  2. Toast the caraway and coriander whole, grind, then weigh. Rung 3. In a paste that will sit in a jar for a month, a stale spice does not improve with keeping.
  3. Use a mortar. Pounding tears cell walls progressively and releases the oils into the paste as it forms. A blade cuts and aerates, oxidising the volatiles it has just liberated, and it cannot make harissa thick without added liquid, which is what shortens its life.
