For the dressing, whisk all the ingredients together, season with salt, pepper and sugar to taste.
Place the salmon fillet in the freezer for 10 minutes. Slice the salmon thinly and arrange on serving plates, overlapping the slices very slightly. Scatter over the red chilli, spring onion and garlic. Spoon over the dressing and leave to marinate for 5–10 minutes.
Scatter the coriander over the ceviche to serve and garnish with mixed cress if you like.
Thankyou for a lovely recipe. I used the marinated salmon in a light salad. perfect lazy but fancy dinner for our 40 degree celsius heatwave we are broiling in down here in Oz.
