Direct-contact cooking using geothermal heat retention in basalt stones.
Technical
Basalt's high thermal mass (0.84 J/g°C) and vesicular structure enable gradual heat transfer, causing myofibrillar protein shrinkage (40-60°C) and collagen gelatinization (starting at 60°C) without combustion byproducts.
Culinary Significance
Imparts smoky minerality while preserving moisture through rapid surface searing that seals meat juices.

Key Variables
Failure Modes
Protein adhesion
Cause: Insufficient stone preheating
Visual: Tearing meat fibers on removal
Fix: Achieve Leidenfrost effect (stones >200°C)
Uneven cooking
Cause: Non-uniform stone surfaces
Visual: Charred spots with raw patches
Fix: Select stones with <3mm surface variation
