I think of this tomato relish as a beginner’s guide to sambal, as it works beautifully either spicy or mild, depending on your preference. For those with chilli-sensitive palates, like my Devonshire mother-in-law, Caroline, deseeding the chillies lowers the potency of the heat. The addition of tomatoes makes it a mellow and umami-rich relish that is irresistible drizzled over soups, added to stews or used as a dipping sauce with wedges or fritters.
This is typically made with intensely flavoured bush tomatoes in the parts of Indonesia where they are lucky enough to grow them, but in my home kitchen in London I’m happy to use good-quality cherry tomatoes.
This sambal keeps for up to 1 week in the fridge covered with a thin layer of sunflower oil, or for up to 3 months in the freezer.
