It may be the cold weather.  It may be the much-needed rest after the holidays.  Or maybe it’s the marathon of Cupcake Wars you saw over the weekend.  Regardless, there’s something about January that inspires warm, home-baked meals.  It doesn’t have to be complicated either; the breakfast Strata can be made the night before, and is a crowd pleaser with savory ham, gooey cheese and spinach for good measure.  Panettone is a seasonal sweet offering, where we found the best at Emporio Rulli, hailing from San Francisco. Our favorite is the Panettone Paradiso, a Milanese classic with a modern twist of added bits of Valrhona chocolate, walnuts and golden raisins.  All you need are friends, who can stop by at their leisure and help themselves to your brunch buffet.
