To remove the seeds and fibers from tamarind pulp start with a cup of pulp and one cup of boiling hot water. Place the pulp in a bowl and cover with the boiling water. Let it sit for about 20 minutes. Remove the pulp with a slotted spoon and place in a fine strainer. Use your fingers or a spatula to mash and push the pulp through the strainer. You can use the paste immediately or cover and refrigerate for later use.
