Step 1

In a small bowl, whisk the lemon juice, mustard, garlic, salt and pepper until combined. Slowly pour in the olive oil while whisking, to emulsify. Alternatively, you can make this in a jar with a tight-fitting lid. Simply add all the ingredients, cover, and shake vigorously to combine.

Step 2

Use within a couple of hours or refrigerate in a sealed container for up to two weeks. Bring to room temperature and re-whisk or shake in a covered jar before using.
