Cook like a chef "second part"

Just buy dirty vegetables, in these day, fresh is more important than organic, so buy veg. that look like they are still attached to the earth. Try to buy fresh, local and in season. In tomatoes find a farmers market heirloom that feels firm, not soft, which means it full of liquid and the flavor will more concentrated. Butter is good, Too many cookbooks say butter, butter and more butter and some person have afraid to use but if you uses a real good butter is really good for you. Use only unsalted butter, with butter is possible do hundred of good sauces like hollandaise.
