Mix all ingredients (except water) in a bowl and pound lightly with a wooden spoon. Mix well.
Place into 1 pint size jar and press down with wood spoon or fist until liquid completely covers tomato relish.
If needed, add a bit more filtered water to ensure coverage, leaving at least 1 inch of head space.
Tighten lid and leave at room temperature for 2 days.
Transfer to refrigerator. Will stay for 1 month in fridge.
