Tip: Long-grain rice is best when cooked and chilled 1 day before making the Nasi goreng. Note 1: Sambal oelek, from Indonesia, is made from chopped chillies and vinegar with no other flavourings added. It has a high heat rating, and is available in jars in Asia grocery stores and some supermarkets. Once opened, sambal oelek will keep stored in the fridge indefinately. Note 2: Fried shallots have a golden colour and crisp, crunchy texture. They're often used as a garnish, but can also be sprinkled over salads, curries, or rice noodle soups. Store in the freezer to prevent them from becoming rancid.
