The rabat (fold, or stretch and fold) is a gentle dough manipulation performed during bulk fermentation that serves as a substitute for, or supplement to, mechanical kneading — building strength, structure, and organisation in the dough through periodic stretching and layering rather than continuous mechanical action. This technique has become central to artisan French boulangerie, particularly for high-hydration doughs that would be damaged by extended mixing. The basic motion is deceptively simple: the baker wets their hands (to prevent sticking), slides their fingers under one edge of the dough mass, stretches it upward as far as it will extend without tearing (typically 30-40cm), then folds it over the remaining dough. This is repeated from each of the four sides (north, south, east, west), constituting one complete fold. A series of 3-4 folds is performed at intervals during pointage, typically every 30 minutes for the first 1.5-2 hours of a 3-4 hour bulk fermentation. Each set of folds accomplishes several things: it stretches and aligns the gluten strands, building extensibility and strength without the oxidation caused by mechanical mixing; it redistributes yeast, bacteria, and their food sources (sugars) throughout the dough, ensuring even fermentation; it equalises temperature, eliminating warm and cool spots; it partially degasses the dough, preventing individual gas cells from growing too large too early; and it introduces layers into the dough structure that contribute to the open, irregular crumb characteristic of artisan bread. The change in the dough over 3-4 sets of folds is remarkable: it transforms from a slack, sticky mass into a smooth, cohesive, moderately taut dough with visible bubbles beneath the surface. For high-hydration doughs (75%+), folds may be the only structural development the dough receives, replacing mechanical mixing entirely in methods like the Tartine or Chad Robertson approach. For standard hydration doughs, folds complement a shorter mix, reducing total mixer time while improving flavour and crumb structure.
Stretch each edge upward and fold over centre, from all four sides. Wet hands to prevent sticking. 3-4 fold sets at 30-minute intervals during first half of bulk fermentation. Builds strength without oxidation of mechanical mixing. Redistributes yeast and equalises temperature. Can replace or supplement mechanical kneading.
The dough tells you when it’s had enough folds: when it becomes noticeably tighter and resists stretching (the edge tears rather than extending smoothly), stop. For very wet doughs, the coil fold is an excellent alternative: lift the dough from the centre, allowing the edges to fold under from gravity, then set down. This avoids the sticking issues of traditional stretch-and-fold on very slack doughs.
Tearing the dough by stretching too aggressively. Folding with dry hands, causing sticking and tearing. Performing folds too late in fermentation when the dough is fully expanded and fragile. Too few folds, leaving the dough underdeveloped. Too many folds, over-tightening the dough and compressing gas cells.
