Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Tuna
Forms the main body of the dish and is kept raw, so it must be very fresh.
Coconut milk
Adds richness and fat to the dressing, giving a creamy, smooth texture.
Dijon mustard
Emulsifies the oil and lime juice, helping the dressing stay smooth and combined.
Fresh lime juice
Provides acidity that gives the dressing its bright, tangy flavour.
Avocados
Contributes creamy fat and a soft texture that contrasts with the tuna.
Corn nuts
Add crunch and a toasted corn flavour when ground and dusted over the avocado.

The step that matters

Keep the tuna and avocado cold until serving. Raw tuna is safe and tender only when kept cold, and avocado flesh browns through oxidation once exposed to air. Refrigerating the sliced avocado under plastic wrap limits discolouration and keeps the fish firm.
