2egg yolks
200mlfish stock
1-2tsplemon juice
olive oil and butter for frying
fine sea salt
Instructions
Begin with preparing the wild garlic oil. Carefully rinse the wild garlic, then blanch for 30 seconds in a pan of salted boiling water. Drain and plunge the leaves into iced water. Once cold, thoroughly pat dry.
Chop the wild garlic roughly, add to a blender and pour in the oil. Blitz briefly on a low speed, then increase in speed for 30 seconds until the oil is a bright, vibrant green colour.
Pass through a fine sieve lined with a muslin. Transfer to a suitable sterilised container and store in the fridge until required.
Pour the stock into a pan, reduce by half, set to one side.
To make the emulsion: whisk together the egg yolks, mustard and vinegar in a bowl with a pinch of salt until smooth. Weigh out 200ml of the wild garlic oil and add this to the bowl in a slow steady stream, whisking continuously, until the mixture has emulsified to form a green mayonnaise. The consistency should be that of double cream so you will most likely need to add a little of the reduced fish stock to loosen it. Season to taste. Take 30ml of the remaining garlic oil to make the wild garlic dressing, add 1-2 teaspoon of lemon juice and taste, if you feel it needs more acidity add a little more juice, pour into a jam jar and set to one side.
Sprinkle a little fine sea salt on each piece of cod.
Heat a cast iron frying pan to a medium-high heat, add little sunflower oil. Place the fish in the pan, after a minute or so add a tablespoon of butter. When the fish is three quarters cooked flip it over, add a 2-3 of tablespoons of the reduced stock, cook 30 seconds longer then turn the heat off. In the meantime boil or steam the asparagus and have 4 warm plates ready. Place the vegetables on the plate, arrange the cod on top. Swirl a little of the wild garlic emulsion around the plate and give the dressing a good shake before drizzling the dressing around the plate. Garnish with a wild garlic leaf and flowers if desired. Serve with new potatoes.
Notes
*Sadly I can't give precise timings on the cooking of the fish as size and thickness varies.
