This is a sure-thing aioli, that is simple to make. It isn’t too strong on the mustard/wasabi flavor and is quite versatile. It will stay in emulsion for a few days. Remember to refrigerate!

In a medium bowl, whisk together the mayonnaise with the lemon juice, salt and pepper. Slowly start to drizzle in the mustard seed oil, continuing to whisk until the mixture is completely emulsified. Refrigerate.
