The example at Lisleagh in County Cork fits this pattern precisely: a low, circular mound of burnt material roughly ten metres across and just thirty-five centimetres high, with a central depression approximately three metres in diameter and of similar depth. Unassuming to the point of near-invisibility, it would not detain most walkers for more than a moment.

A fulacht fia, the term used in Irish archaeology for these Bronze Age cooking sites, typically consists of a horseshoe-shaped or circular mound of heat-shattered stone and charcoal built up around a trough, usually timber-lined or cut into the ground. The method, as reconstructed by experiment, involved heating stones in a fire and dropping them into a water-filled trough until the water boiled, at which point meat could be cooked. The shattered, fire-cracked stones were discarded to the sides, gradually forming the characteristic mound. Thousands of these sites survive across Ireland, with particularly dense concentrations in Munster, suggesting they were a routine feature of Bronze Age land use rather than anything ceremonial or rare. The depression visible at the Lisleagh example almost certainly represents the site of the original trough, now filled in but still legible as a hollow at the mound's centre.
