spider web patterns used on some deserts and pastries. It's made by alternating different colored sauces - then drawing lines through them with a toothpick or other. I know there's a French term for this but can't recall it.
You're right- the sauces used could be coulis or colored creams, chocolate,etc - but what is the technique called to create the spider webs patterns on top of the pastries, cakes,etc? I keep think it starts with a "P".
