Vendors judge it done not by taste but by height — a proper aligot should stretch in an unbroken ribbon well over a meter when lifted with a spoon.
Aligot is mashed potato beaten vigorously with fresh Tomme cheese, garlic, and butter until it turns into a smooth, elastic mass that stretches like taffy when pulled. Market stalls and fairs on the Aubrac plateau serve it ladled straight from huge pots, still being stirred.
