4 Tbsps white or dark balsamic vinegar ( I like dark)
Directions Preparation:4min › Extra time:11min › Ready in:15min
Boil the first lot of ingredients – the mustard seeds, white vinegar, cornflour and boiling water - in a saucepan on the stove, stirring till thick, then take the pot off the stove.
In blender mix together the second lot of ingredients – the egg yolks, sugar, salt and vinegar.
Then slowly add the first lot of ingredients to the second in the blender, as a dribble, while blender is running. Note: the first lot of ingredients don't have to be cooled down for any longer than it takes to process the second lot of ingredients.
When they are all blended together, drizzle in the oil and vinegar, then blend well.
