Step 1 Place the eggplant in a large colander, sprinkle with the salt and toss to combine. Place the colander in the sink and stand for 1 hour for the eggplant to degorge. Rinse the eggplant well and pat dry with paper towel.
Step 2 Combine the eggplant, capsicum, onions, dates, vinegar, brown sugar, chillies, garlic and cumin seeds in a large heavy-based saucepan (about 4-litre/16-cup capacity). Stir over high heat until the sugar dissolves. Bring to the boil.
Step 3 Reduce heat to medium-low and boil gently, stirring occasionally, for 1 1/2 hours or until all the excess liquid has evaporated and the mixture is thick. Stir the chutney more frequently towards the end of cooking.
Step 4 Remove the saucepan from the heat and stand for 2-3 minutes. Stir and then ladle into hot sterilised jars. Seal tightly and turn upside down for 2 minutes. Invert and allow to cool. Label, date and store in a cool dark place for at least 1 month before using.
Step 5 Serve with aged cheddar on crusty bread, with Indian curries, on roast beef sandwiches, with roast vegetables or pork, or add a spoonful to chunky vegetable soups.
Step 6 This chutney will store in a cool, dark place for 6 months. Once opened, keep in the fridge for up to 8 weeks.
