Note 1: To make the raspberry reduction, start with 1 1/2 cups (190 g) fresh or frozen raspberries. In a small saucepan, cook the raspberries on medium-high heat until they have released their juice and part of the liquid has evaporated. Pass the raspberry mixture through a sieve to remove the seeds and skin. Return the raspberry juice to the saucepan and cook further until it has decreased in volume to about 1/3 cup (about 60 g).
