Coriander and Lime Tartare Sauce

Begin by breaking the egg into a processor or blender.

Add the salt, garlic and mustard powder, then switch the motor on and, through the feeder tube, add the oil in a thin, steady trickle, pouring it as slowly as you can (it takes about 2 minutes). When the oil is in and the sauce has thickened, add some pepper and all the other ingredients. Now pulse until the ingredients are chopped – as coarsely or as finely as you want.

Lastly, taste to check the seasoning, then transfer to a serving bowl.
