Mustard (condiment) The second element comes also from Latin "ardens", (hot, flaming). It was first attested in English in the late 13th century, though it was found as a surname a century earlier. Archeological excavations in the Indus Valley (Indian Subcontinent) have revealed that mustard was cultivated there. That civilization existed until about 1800 BC. The Romans were probably the first to experiment with the preparation of mustard as a condiment. They mixed unfermented grape juice (the must) with ground mustard seeds (called "sinapis") to make "burning must", "mustum ardens" — hence "". A recipe for mustard appears in "De re coquinaria",
High-altitude cooking High-altitude cooking High-altitude cooking is cooking done at altitudes that are considerably higher than sea level. At elevated altitudes, any cooking that involves boiling or steaming generally requires compensation for lower temperatures because the boiling point of water is lower at higher altitudes due to the decreased atmospheric pressure. The effect starts to become relevant at altitudes above approximately . Means of compensation include extending cooking times or using a pressure cooker to provide higher pressure inside the cooking vessel and hence higher temperatures. At sea level, water boils at . For every increase in elevation, water's boiling point is
