A pre-cut block of frozen yellowfin tuna in the standard saku format — rectangular, uniform, and ready to slice straight from the fridge once thawed. A practical, affordable option for sushi nights, poke bowls, or a quick sear. Not the most complex tuna you will eat, but consistent, clean-tasting, and easy to work with at a price that makes sense for midweek cooking.

£18.00

A pre-cut block of yellowfin tuna (Thunnus albacares), frozen and portioned into a uniform rectangular saku shape for easy slicing. This is a practical, entry-level tuna — clean-tasting and lean, with a firm texture that holds up well when sliced for sashimi or seared quickly in a hot pan. It is not in the same league as a hand-cut loin steak from a line-caught fish, but for everyday sushi nights, poke bowls, or a quick midweek sear it does the job reliably and at a sensible price point.

Saku blocks are the standard format used in sushi restaurants for high-volume slicing — the rectangular shape means uniform, consistent slices with minimal waste. The block arrives frozen and should be thawed slowly in the fridge before use. Once thawed, it is ready to slice straight from the pack. If searing, pat it thoroughly dry first.

Ingredients: Yellowfin tuna (Thunnus albacares).

Storage: Shipped frozen in insulated packaging. Store in the freezer at -18°C or below. Thaw slowly in the fridge — allow 8–12 hours. Once thawed, use within 2 days. Do not refreeze after thawing.

Allergens: Fish (tuna).

Thawing: Remove the block from the freezer and place it in the fridge on a plate or tray, still in its packaging. Allow 8–12 hours for a full thaw. Do not thaw at room temperature or in warm water — slow, cold thawing preserves the texture.

For sashimi or sushi: Once fully thawed, unwrap the block and pat it dry with kitchen paper. Using a sharp knife, slice against the grain into pieces approximately 5mm thick. Serve with soy sauce, freshly grated wasabi if you have it, and pickled ginger. The rectangular saku shape is designed for this — consistent slices with no awkward angles.

For seared tuna: Pat the thawed block thoroughly dry — this is the most important step. Season lightly with salt and pepper, or press one side into a mix of black and white sesame seeds. Heat a pan (cast iron or heavy-based) until it is smoking hot. Add a thin film of a neutral oil with a high smoke point. Sear for 30–40 seconds per side — no more. The centre should remain completely raw. Rest for a minute, then slice across the grain into 1cm pieces. Serve with a soy and ginger dipping sauce, or ponzu.

For poke bowls: Cut the thawed block into roughly 1.5cm cubes. Toss with soy sauce, sesame oil, a squeeze of lime, thinly sliced spring onion, and a pinch of chilli flakes. Serve over warm sushi rice with avocado, edamame, and pickled radish.

For tartare: Dice the thawed tuna finely — 5mm cubes. Mix with a small amount of soy sauce, a few drops of sesame oil, finely chopped shallot, and a little grated fresh ginger. Serve on toast, in lettuce cups, or shaped with a ring mould alongside a simple salad
