For the best authentic texture, cook the macaroni softer than al dente so it can absorb the creamy dressing as it chills, which is key to Hawaiian-style macaroni salad. Use full-fat mayonnaise for richness and avoid light or low-fat versions, which can make the salad watery or less flavorful. Grating the onion instead of chopping it helps its flavor distribute evenly without leaving large, pungent pieces. The salad often tightens up in the fridge, so don’t be afraid to keep it looser and extra creamy before chilling, then refresh it with a splash of milk or another spoonful of mayo just before serving. This dish tastes best well-chilled and is ideal to make several hours or a day ahead for serving with plate lunch favorites like grilled meats or teriyaki chicken.
