I serve this slightly sweet mustard dill sauce usually with fish such as mackerel and salmon.
3 tbsp wholegrain mustard
2 tsp white wine winegar
1 egg yolk
1 tbsp caster sugar
1/4 tsp white pepper
200ml rapeseed oil
60g dill
1. Mix together all ingredients apart from the oil and dill.
2. Pour the oil in on a continuous, thin stream, whisking properly at the same time. Make sure the oil gets fully incorprated onto the other ingredients.
3. Chop the dill very finely, and add to the sauce.
4. Chill in the fridge before serving.
