Tagliolini with Porcini Sauce

We celebrated a friend's birthday the other night at one of my favorite recent additions to the Seattle restaurant scene, a cozy little trattoria called Cascina Spinasse. Four hours later, after multiple courses and wines—and a midnight votive incident that luckily didn't torch the place—we stumbled home. But the next day I just had to call the restaurant to ask them about their porcini pasta.
