A blender purees and mixes food with rotating blades. It is a tall container with a blade at the bottom. The motor spins the blade at high speed. The food is pulled down into the blades and chopped, whipped, or liquefied. The blender is a versatile appliance. It makes smoothies, soups, sauces, and baby food. It crushes ice. It grinds spices. It emulsifies dressings. It is not the same as a food processor. A food processor has a wider bowl and different blades, designed for chopping and shredding. A blender is designed for liquids.

Blenders come in several types. A countertop blender has a heavy base and a large jar. A immersion blender, also called a stick blender, is handheld and used directly in the pot. A high-powered blender, like a Vitamix, can pulverize nuts and seeds into smooth butter. A personal blender has a smaller jar that doubles as a travel cup. The choice depends on the volume and the task. A stick blender is convenient for soup. A high-powered blender is better for nut butter.

The order of ingredients matters. Liquids go in first, then soft ingredients, then hard ingredients, then ice. That keeps the blades moving and prevents air pockets. Do not overfill the jar. Hot liquids can erupt and burn. Vent the lid. Start on low and increase the speed. The blender is a simple machine. It is also a powerful one. It can turn a handful of ingredients into a smooth, silky puree in seconds. The blade does the work. The cook does the thinking.
