Taragna polenta is made from ground corn and buckwheat.
The black bits in it are the buckwheat, which give it a slight bitter flavour.
It is popular in Lombardy, Italy.
In different areas of Lombardy, it is served cooked with different cheeses on it — Taleggio, Bitto cheese in Valtellina, Branzi cheese around Bergamo, etc.
It is served with thickly cut cold cuts, or with sausage.
