Rodgers' polenta documentation challenges the instant polenta shortcut with a specific argument: the long cook (45 minutes minimum of constant stirring) develops a sweetness and complexity in the cornmeal that instant polenta — pre-cooked and dried — cannot replicate. The starch granules rupture gradually over the long cook, releasing sugars and producing a creamy texture from the grain itself rather than from added dairy.
Coarsely ground cornmeal cooked in salted water or stock at a ratio that produces a pourable consistency when hot and a set consistency when cold, stirred constantly for 45 minutes minimum at a gentle simmer, finished with butter and parmesan.
- Ratio: 1 part polenta to 4–5 parts liquid for soft, pourable polenta. 1:3 for firm, set polenta [VERIFY ratios] - Whisk in the polenta in a steady stream to prevent lumps — lumps formed at the beginning cannot be eliminated by stirring and persist through the cook - Cook at a gentle simmer, not a boil — boiling polenta spits and causes burns. The correct temperature produces occasional large bubbles that break slowly at the surface [VERIFY temperature] - Stir constantly — unattended polenta sticks to the base and burns before the centre is cooked. The constant stirring also develops the creaminess through mechanical action on the starch granules - Season heavily — polenta absorbs salt less efficiently than most preparations. Taste aggressively and adjust - The finish: butter worked in off heat, then parmesan — both added after removing from heat to prevent the fat from separating Decisive moment: The detachment test at 45 minutes — properly cooked polenta pulls away from the sides of the pot as a cohesive mass when stirred. Undercooked polenta remains sticky and clings to the pot walls. The taste should be sweet and complex, not starchy or raw.
