Old Style Sauce

This sauce can be prepared up to 4 hours ahead and refrigerated in an airtight container. The foam will deflate slightly upon standing, so give it a quick re-whisk for 30-60 seconds before serving to restore volume and lightness.

Store in an airtight container in the refrigerator for up to 2 days. The sauce will lose some volume over time as air bubbles escape. Whisk briefly before serving to refresh the texture, though it will not achieve the same initial lightness as when freshly made.
