Heat the oven to 425 degrees. Drain the pears, reserving the juice. Combine
the sugar, cornstarch, and cinnamon in a saucepan, then add the pear juice and lemon
juice. Heat until the mixture thickens to syrup, then boil for 1 minute.
Remove pan from heat and add the pears. Spoon the pears and syrup into a
9-inch square baking dish. In a medium bowl, combine the flour, sugar, baking
powder, salt, and cheddar cheese, mixing well. Add the butter and milk, mixing until
well blended. Spoon the dough over the pears, then bake for 30 minutes.
