Use this basic recipe for toppings and variations of all kinds.
Bring the stock to a boil in a tall-sided saucepan (the polenta likes to spit and gurgle and jump out of the pot). Add the salt, and while whisking over medium-high heat, add the polenta in a slow and steady stream.
Reduce the heat to a gentle simmer and stir occasionally for about 30 minutes or longer, up to 1 hour. Feel free to adjust the consistency by adding more stock, water or even milk or cream. Taste for salt and adjust, and then whisk in the olive oil. Serve hot.
