Roasting vs Steaming: Concentration vs Preservation

The choice between roasting and steaming a vegetable is not merely a cooking method choice — it determines whether the cooking concentrates the vegetable's flavour (roasting: water evaporates, sugars concentrate, Maillard develops) or preserves it (steaming: water-soluble nutrients and volatile aromatics are largely retained, no Maillard). Both are correct; the choice depends on what the vegetable needs to express.
