As for the preparation, I happened to have US measuring cups (another gift from my sister - in - law)- 1 cup polenta = 163 g (I measured it on my scale but one internet site said the conversion of 1 cup cornmeal should be between 128 - 130 g) and 1
tbsp butter = 15 g. I have halved the recipe because making a dozen is just too many for us to finish.
