Peel the pears. Put them in a small saucepan with the cinnamon, 1 tablespoon sugar and enough water to cover them. Cook on medium heat with the lid cracked, until they soften. The amount of time will vary depending on the type of pear. Test it with the tip of a sharp knife. When you feel they're soft, turn off the heat. Cool the pears in the cooking water. You can do this the night before.
