The invention provides a method for the preparation of a foamed drink
comprising the steps of: providing a capsule containing a foamable
ingredient; providing a receptacle positioned to collect fluid escaping
from the capsule; injecting liquid into the capsule to mix with the
foamable ingredient; allowing the foamable ingredient mixed with the
liquid to escape from the capsule into the receptacle; followed by
injecting further liquid into the receptacle in a jet having a diameter
of from about 0.5 to about 2 mm to produce foamed liquid in the
receptacle. The invention also provides capsules, apparatus and systems
specifically adapted for use in the method. Preferably, the food
ingredient is a milk powder, and the method produces a hot foamed
beverage such as a cappuccino coffee.
