1. Bring a medium pot of water to a rolling boil. Meanwhile, fill a medium-size bowl with ice and cold water, and set it near the stove. Add the spinach to the boiling water, pushing down with a slotted spoon to fully submerge, and blanch until leaves turn dark green, about 1 minute. Quickly transfer spinach to the prepared ice bath to halt cooking.
2. Drain spinach well and squeeze out any excess water. Transfer to the bowl of a food processor and purée until smooth
