1. Peel and core the pears. The grittiness that pears can sometimes have is concentrated just under the peels, so peeling the fruit makes a big difference in the texture of your final product.
2. Cut the peeled and cored pears into 1-inch chunks.
3. Put the pears, water, lemon and honey or sugar (if using) into a slow cooker.
4. Cover and cook on high for 4 to 5 hours. The pears should become very soft.
5. Transfer the pears to a blender or food processor using a slotted spoon. Reserve the cooking liquid left in the slow cooker.
6. Purée the pears. Add cooking liquid as necessary to achieve a thick but spreadable consistency.
7. Spoon the pear butter into clean half or quarter-pint canning jars.
8. Use a butter knife or a spoon to press out any air bubbles. Leave 1/8-inch of head space.
9. Wipe the rims of the jars clean and screw on the canning lids.
10. Process in a boiling water bath for 20 minutes (adjust the time for your altitude if necessary).
