Toss pears with lemon juice in a medium bowl. Melt butter in a
large deep skillet or Dutch oven over medium heat; stir in the pears.
Reduce heat to medium-low, cover and cook, stirring once halfway
through, for 10 minutes.
Meanwhile combine sugar, cinnamon, ginger, cloves and salt in a
small bowl. After 10 minutes, stir the sugar mixture into the pears.
Increase the heat to medium and cook, stirring often, until the
pears are tender and glazed, 4 to 6 minutes, depending on the type
and firmness of the pears. Serve warm.
