Wash the pear with water. Peel the pears using a peeler. Take a sharp knife and cut around 1/2 inch from top to remove the stem. Then place the pear on a chopping board and cut it into half from the centre vertically. Cut each half portion into 2 to 3 more long pieces and remove the seeds and inedible fibrous part from the centre using a sharp knife. Line the pear pieces and roughly chop them into cubes using a sharp knife. Combine 1 1/2 cups roughly chopped pear along with 1/2 cup water in a blender and blend till smooth. Strain and use immediately.
