In a large stainless-steel pot, combine all the ingredients except for the salt and baking soda. Bring the mixture to a boil over high heat, then reduce to medium-low heat. Simmer gently for about 20 minutes, stirring occasionally. Allow the mixture to cool for at least 15 minutes before adding to the food processor or blender.
Puree the sauce in batches, then press the sauce through a fine sieve for a smooth finish. Stir in the salt and baking soda, which will help to balance the acidity of the sauce.

Meanwhile in a medium-sized stockpot over high heat, bring the sugar, vinegar, mustard seed, celery seed, cloves, and turmeric to a boil. Reduce the heat to medium-low and add the drained cucumber, onion and hot pepper. Cook until the mixture thickens, about 20 minutes.
