Combine the morels with 2 cups (500ml) water in a medium-sized saucepan. Bring to a boil over high heat, then allow to cook away vigorously, uncovered, until the liquid is reduced by half. This will take about 20 minutes. Remove the morels with a slotted spoon. Strain the liquid through a double thickness of dampened cheesecloth. Return the morels to the reduced liquid, and reserve.
