Use a handheld whisk
Choose a tall container with room for the milk to expand. Dip the whisk head into the milk before switching it on. Start just below the surface, then move a little deeper. Holding the whisk at the surface can make large bubbles. Switch it off before pulling it out.
For a warm cappuccino, warm the milk in a suitable container first if the whisk is designed for warm milk. Avoid boiling it. The movement of the whisk affects the result. With a plunger, the number of strokes is the main way to vary how much air you add.
Use a plunger frother
Follow the fill mark and use steady strokes. Bodum designed the Latteo for frothing cold milk. Its instructions describe optional warming in the appropriate glass afterwards. With another model, check the guidance for its material and temperature limits.
Pour the foam and milk together
Tap the container gently on the worktop and swirl to bring the milk and foam together. Pour it into the espresso. If most of the foam sits on top in a stiff layer, try frothing for less time. Compare with the same amount of milk in both attempts.
Try plant-based drinks
Plant drinks foam differently depending on their formulation. Use the same amount, temperature and technique to compare them. Look for one that mixes well with your coffee. Rinse the equipment after use as directed so milk does not build up in the whisk or mesh.
