The most successful choices are coulis that set off the flavours and colours of your desserts, whether you complement or contrast. Then you need to work out the design you wish to make with the coulis. The ideas below are a starting point.
Drizzling on to a plate
Overlapping rings of white chocolate sauce and raspberry coulis are drizzled from a spoon and allowed to blend.
Pooling coulis
A dessert can be served sitting on a pool of coulis. Use the back of a spoon to spread out a circle of coulis on a plate.
