In many cases, a blender can be used in the same way as a food processor as long as you are willing to work with smaller batches. A blender can handle most tasks that a food processor can with the exception of kneading dough and making pastry dough. With a bit of practice, most recipes that call for the use of a food processor can be processed in a blender.
Break up two to three slices of dried bread into quarters. Place three or four bread quarters in the blender jar. Process into breadcrumbs on pulse until the desired sized crumbs are achieved. If your blender doesn't have a pulse button, run the blender on high for a 30 seconds at a time. Repeat with the remaining bread quarter. This will yield approximately 62 g (1/2 cup) of breadcrumbs, depending on the size of the bread.
Make your own baby food by placing 40 g (1/4 cup) of freshly cooked vegetables in the blender jar. Turn the blender on purée or high and blend until smooth.
Grind or shred cheese in the blender by dicing hard cheeses into 5 to 7.5 cm (2 to 3 inch) chunks. Place in the blender and turn to high for 30 seconds to a minute or until the cheese reaches the desired consistency.
Make homemade pesto by placing 178 ml (3/4 cup) of extra virgin olive oil, 75 g (3/4 cup) Parmesan cheese 40 g (2 cups) basil leaves, 3 minced garlic cloves, and 31 g (1/4 cup) pine nuts in the blender jar. Turn the blender on medium and process until smooth and creamy.
Chop ice for mixed drinks by placing four to five ice cubes in the blender jar. Turn the blender on high and process until the cubes are finely chopped.
Some blender models have a food processor accessory attachment that can be bought separately and used with the blender base. Even working in the smaller batches required for using a blender as a food processor, it is still a time saver over doing the tasks by hand.
Some inexpensive models of blenders may not be able to handle chopping ice or shredding hard cheese. The motor in inexpensive blenders is not powerful enough to do these tasks.
