Yuzu Kosho with Wagyu: Using a Little Well

Yuzu kosho is a concentrated paste of citrus peel, chilli and salt, though formulas differ. Check the label before adding any salt to the ribeye. Stir the quarter teaspoon of paste with the citrus juice, water and oil. This produces a light dressing that can be dosed by the teaspoon rather than spread directly from the jar.

A measured yuzu-kosho finish for two

• Japanese Wagyu Ribeye, A5, 200g
• ¼ tsp yuzu kosho, then more only if needed
• 2 tsp fresh lemon or yuzu juice
• 2 tsp water
• 1 tsp neutral oil
• 60g finely shredded daikon or cucumber
• 1 spring onion, thinly sliced

Method

1. Prepare the daikon or cucumber and spring onion. Keep them chilled while the beef cooks.
2. Pat the intact ribeye dry. Sear all exterior surfaces in a hot pan and follow the pack instructions and current safety guidance for the centre. Rest on a clean board.
3. Slice across the grain. Divide the vegetables and beef between two plates, then spoon half a teaspoon of dressing beside each portion. Taste before adding more.

Do not put yuzu kosho into the searing pan: the wet paste can spit, scorch and make the salt difficult to control. The common mistake is treating it like a mild citrus sauce; a small amount can dominate a tasting portion. Record the paste brand and declared salt content during the kitchen test because changing brands may require a different dose. Refrigerate the opened condiment as its label directs.

Key takeaways

• Check the cut, format and serving plan before choosing a pack.
• Keep origin, cut, grading, pack format and cooking method distinct.
• Confirm current product specifications and availability on the live listing.

Ingredients

Amounts below are a planning guide; adjust them to the actual pack weight and number of diners.

• 1 tbsp neutral oil
• ½ tsp fine salt
• black pepper
• 1 small shallot
• 1 tbsp unsalted butter
• 1 tsp lemon juice
• seasonal greens, to serve

Method

1. Read the pack instructions first. If frozen, defrost in the fridge and prepare the sides before you start.
2. Sear the steak in a hot, uncrowded pan, turning to brown the outside evenly. Rest it while you soften the shallot in butter; finish with lemon and spoon over the meat.
3. Serve promptly with the planned side. Watch the actual cut and thickness rather than treating a timing as fixed.

How to adjust the method

Check the pack weight, thawed state, thickness and cooking surface before starting. Use a food thermometer where appropriate and adjust the heat if the surface browns too quickly. If the meat steams rather than browns, the pan may be crowded or the surface wet. If the outside darkens before the centre suits your preference, reduce the heat and adjust the method on the next test. This recipe uses 200–250g as its recipe quantity; it is not a claim that the linked product is sold in this exact pack size.

Food safety: this recipe uses an intact steak. The FSA says whole beef cuts can be served pink to preference when the outside is thoroughly seared. That advice does not apply to mince, burgers or rolled meat. Follow the pack and current FSA guidance.
