1. Peel the pears, quarter them lengthwise, and core. Slice pears thinly and place in a saucepan with the apple cider and gingerroot. Add a pinch of salt.
2. Bring to a boil, reduce heat and simmer until pears are tender, about 15 minutes.
3. Dissolve cornstarch or arrowroot in 1/3 cup cold water and add to the simmering pears, stirring, until the sauce is thick and clear.
4. Remove from heat and stir in almond extract. Serve warm or cold.
