Great for summer salads
Using a flavoured oil adds a zingy twist to a classic dressing
In a small bowl, whisk together the mustard, salt and vinegar. Make sure the salt is completely dissolved before adding any oil, as the oil can stop it from dissolving.
Gradually whisk in the oil until it is all blended in, and then stir in the shallot. If you have time to let it stand to allow the shallot flavour to blend in, so much the better!
