Peel and dice the mangoes, cutting them into small pieces for a jamlike chutney, into 1/2" or larger dice for a chunky mixture. Place the pieces in a preserving pan. Add the onions, raisins, currants, ginger, garlic, lemon zest, brown and granulated sugars, mustard seed, salt, crushed hot red pepper, cinnamon, turmeric, cloves, ground red pepper, white vinegar and the remaining 1 cup water; stir the mixture and let it rest until the tamarind "juice" is ready, or for up to several hours, if that is convenient. When the tamarind pulp is very soft, strain the liquid through a sieve, pressing it to remove all possible liquid and any pulp that will pass through. Discard the pulp remaining in the sieve. Add the liquid to the chutney mixture. Set the pan over medium heat and bring the ingredients to a boil. Lower the heat so the mixture simmers and cook it, uncovered, stirring often, until the mango and onion pieces are translucent and the chutney has thickened to the consistency of preserves, 1 to 2 hours depending on the firmness of the fruit. (The chutney will thicken further in the jar, so don't reduce it too much.) If the chutney threatens to stick before the mango pieces are translucent, add a little water. Remove chutney from the heat, cool a sample, and taste it for tartness, sweetness, and degree of hotness. (The overall flavor is elusive at this point, but these factors can be judged.) If you wish, add a little more vinegar, sugar or ground hot red pepper. Reheat the chutney to boiling and ladle it into hot, clean pint or half-pint canning jars, leaving 1/4" of headspace. Seal the jars; process for 15 minutes (for either size jar) in a boiling-water bath. Cool, label, and store the jars for a least a month so that its many flavors can blend and balance. This will keep for at least a year in a cool pantry. Yield: 6 to 7 cups. From _Fancy Pantry_ by Helen Witty. New York: Workman Publishing Company, Inc., 1986. Pp. 56-58. ISBN 0-89480-037-X.
