What You're Doing

Processing ingredients in a blender or food processor until they reach a smooth or uniform consistency. Mechanical shearing breaks down fibres and emulsifies liquids for sauces, soups, and purées.

Visual Cues

Look for these signs to know your technique is working:

  • Mixture becoming smooth and uniform
  • Vortex forming in the blender
  • No visible chunks remaining
  • Colour becoming even throughout

Why It Works

High-speed blades shear cell walls and break fat into microscopic droplets, creating stable emulsions and smooth textures. The mechanical energy also generates slight heat, which can bloom starches for thickening.

Failure Modes

Avoid these common problems:

  • Not enough liquid - blender stalls or creates air pockets
  • Over-blending starchy soups - gluey texture
  • Lid not secure - hot liquid erupts
  • Wrong speed - chunks remain or mixture overheats

Requirements & Guidelines

  • Add enough liquid for the blades to catch
  • Blend in batches if the vessel is more than two-thirds full
  • For hot liquids, vent the lid to release steam
