Where does “risotto” come from?

I need to trace this chain carefully, but I notice the etymology provided has some issues—the chain appears broken or incorrect (Latin ridere "to laugh" and Latin sapere "to know" don't logically connect to rice/risotto, and the PIE roots seem disconnected from the Italian culinary term).
