If you aren’t going to use this sauce immediately after whisking it together then you will want to throw it in the fridge. You can either leave the sauce in the mixing bowl and cover it with plastic wrap or transfer it to an airtight rubbermaid container. When stored properly, your sauce will stay fresh for about 2 weeks. Before using your sauce, give it a quick stir to ensure that the ingredients are fully combined. We often find that the flavors continue to combine as the sauce sits in the fridge.
