For a deeper, more complex flavor, consider caramelizing the onions before puréeing them. This will add a touch of sweetness and richness to the sauce. Adjust the amount of black pepper and sugar to your liking. Some prefer a spicier sauce, while others prefer a slightly sweeter one. If you don't have celery salt, you can substitute with a combination of regular salt and a pinch of celery seed. This sauce can be made ahead of time and stored in the refrigerator for up to 5 days, or frozen for longer storage. Be sure to cool completely before storing. For a smoother sauce, use an immersion blender to blend the sauce after it has simmered for the second time.
