What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1For a milder onion flavor, place the diced onions in a fine-mesh sieve and rinse under cold running water for 30 seconds. Drain thoroughly and pat dry before mixing with cilantro.
- 2Always use freshly squeezed lime juice. Bottled juice has a different, often harsher flavor that doesn't work as well in this fresh preparation.
- 3The ratio is a guideline. Feel free to adjust the amount of onion, cilantro, or lime juice to suit your personal taste.
- 4This topping is best enjoyed fresh on the day it's made to maintain its crisp texture and vibrant flavor.
