The nutty flavour of the California walnuts works extremely well against the acidity of the grapefruit, and alongside the delicate flavours of the tuna and avocado. By its nature, a poke bowl consists of sushi rice topped with raw fish and vegetables – the inclusion of California walnuts in this trendy dish prove how versatile this nut can be, whilst showcasing the creamy flavour.
