This is the Koikeya Niche Rich Garlic Oyster & Mackerel, a crinkle-cut chip from Koikeya’s premium “Niche Rich” line, built around a seafood ajillo-style seasoning combining oyster, mackerel, and garlic.
The chips presented in varied sizes, approximately 4–6 cm in diameter and around 1.5 mm thick, with a crinkle-cut form. The surface showed a light yellow base coated with orange and darker seasoning flecks. Aroma opened with a pronounced savoury profile, led by dried seafood and garlic.
Initial contact delivered immediate umami, with seafood notes appearing from the outset. The structure fractured with a sustained crunch, supported by the ridged cut. Through the mid-palate, garlic became more prominent, carrying the flavour forward alongside a subtle acidity that lifted the heavier notes. The oyster component contributed a rounded, earthy richness, while the mackerel introduced a more defined, savoury depth. Towards the finish, the mackerel note lingered, accompanied by a slightly oily impression that echoed the character of the fish itself. The potato base remained secondary, acting as a stable carrier without adding significant flavour of its own. Aftertaste carried a gentle heat that built gradually across repeated pieces, remaining controlled but persistent.
Overall, a crinkle-cut chip with a garlic-led seafood umami profile and sustained crunch, resulting in a rich, savoury and progressively warming structure.
