What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1For the best results, use a very sharp knife to dice the onion. This prevents crushing the onion cells, which can release bitter compounds.
- 2Always use fresh lime juice. The flavor is significantly brighter and more authentic than bottled juice.
- 3This topping is best made just before serving to maintain the freshness and crisp texture of the onion.
- 4Adjust the amount of salt and lime juice to your personal preference after letting the mixture rest for a few minutes.
