Ignite the quebracho charcoal or hardwood in a pile to one side of the parrilla firebox. Allow it to burn freely. The fire is not ready for cooking: wait until every piece of charcoal has lost its orange flame entirely and is coated in a white-grey ash. This stage takes 45 minutes to 1 hour. Any orange flame remaining indicates uncombusted volatiles that will deposit acrid, petrochemical compounds on the meat surface. The cue is sight: a uniform white-grey glow with no visible flame.

Rake the prepared embers beneath the parrilla grate. The grate is angled so that rendered fat drains away from the heat source, preventing flare-ups. Set the grate height to establish an indirect, radiant heat environment — meat is never positioned directly over live flame. The governing principle is that distance from the embers, not manipulation of the fire, is the cook's temperature control. The cue is touch: hold a hand at grate level — sustained heat without scorching indicates readiness.

Season the achuras and chorizos with coarse parrillera salt on all surfaces immediately before placing on the grill. Apply salt to beef cuts in the same manner — at the start, not during or after cooking. Salt draws moisture to the surface, forming the characteristic crust. Place mollejas, chinchulines, and chorizos on the grill first; these are served to guests on arrival. The cue is sight: surfaces should begin to colour and fat to render within the first several minutes.

This is where the asado lives or dies. Once the achuras are placed, lay the tira de asado (ribs, bone side down) and the vacío on the grill. From this point, the asador must read the fire continuously — humidity, wind direction, and wood moisture alter the heat plane moment to moment. Raise or lower the grate; shift cuts toward or away from the ember bed; never cover the meat. The ribs require extended cooking at measured distance; the flesh should pull slightly from the bone ends and the surface develop a deep mahogany crust. The cue is sight: a consistent, even colour across the entire surface with no grey or steaming patches.

Add the morcilla to the grill after the inner circle has received their mollejas and chinchulines — the sequence carries social meaning and is not interchangeable. Cook the morcilla gently; the casing should tighten and colour without splitting. The cue is sight: the casing is taut, coloured, and intact.

Place the prized cuts — lomo or entraña — on the grill last, as the embers reach their final, most stable stage of heat. These cuts require less time than the ribs and flanks. The cue is touch: the meat offers moderate resistance to a finger press — neither soft nor rigid.

Remove all cuts to a wooden board. Rest for a minimum of 5 minutes without covering — trapping steam at this stage softens the crust that has been built over the full duration of cooking. Cutting immediately would release a significant proportion of the accumulated juices. The cue is touch: the meat surface is dry and firm, not steaming.

Combine the chimichurri ingredients and the salmuera (coarse salt dissolved in water) separately, and set both on the table. These are not optional garnishes — they are structural components of the meal's flavour architecture, providing acid counterpoint to the fat-rich cuts. Serve the cuts in the order in which they were cooked. The cue is taste: the chimichurri should register as sharp, herbal, and saline against the richness of the meat.
