Acar Timun is an easy 15-minute Indonesian pickle with cucumber, carrot, shallot, and bird's eye chilis. It is sweet, tangy, and crunchy. Serve this as a side dish and it will perk up any dishes.
Prepare vegetables – Slice each cucumber into 4 elongated slices and remove the seeds. Cut the cucumbers, carrot, and shallots into same-sized small cubes. Remove the stem of the chilis.
Mix vegetables – Mix the carrot, cucumber, and shallot cubes along with the chilis. Transfer them into a clean airtight glass container. Set aside.
Make brine – In a medium bowl, combine hot water, salt, granulated sugar, and white vinegar until combined.
Pour the brine into the glass container until the vegetables are fully submerged.
Rest – Keep in the refrigerator once the brine has cooled completely. Rest for 1-2 days for the flavor to develop.
