A food processor has several functions that you may not need in a blender. It has the ability to puree ice and drinks, but it can also chop, slice, grate, shred, dice, and more. You can use a food processor for this purpose, but you should be sure to purchase one that has a blade for cutting dough. Otherwise, you might end up with tough gluten strands. Also, it is important to remember that the blades of a food processor are slower than the blades of a blender.
A food processor can also shred cheese. Fresh cheese melts better than pre-shredded cheese. You can shred vegetables as well, such as potatoes, and make coleslaw or a salad. You can even make pesto sauces, pates, and olive tapenades. You can add fresh ingredients to the food processor, such as roasted garlic and spinach, cashews, and nuts, for a flavorful, creamy sauce.
