I rarely cook traditional risotto, but I love other grains cooked similarly - barley, spelt or split wheat. I find they have more character than rice and absorb other flavours more wholeheartedly.
Polenta is to northern Italy what bread is to Tuscany, what pasta is to Emilia-Romagna and what rice is to the Veneto: easy to make, hungry to absorb other flavours, and hugely versatile.
