The farmhouse loaf made by brothers Louis and Robert Wu is a dense loaf of bread, about 15 inches long, in the shape of an elongated football that is dusted with flour, which makes everything it comes into contact with white. And it is so crunchy that taking a bite may cause scratches in your mouth. This loaf is served in many of the finest Italian restaurants in town and is absolutely the best for dipping in olive oil. Served with nothing but butter, it is addictive, whether it's the day it's purchased or the next day and, once it has begun to harden a little, as toast. There's only one thing wrong with this loaf, and that's that it sells out quickly.
