Yes! This sauce actually tastes even better after it's had a chance to sit in the refrigerator for a few hours (or even a day) to allow the flavors to meld.
2. What can I substitute if I don't have fish sauce?
Unfortunately, there's no perfect substitute that will replicate the umami depth of fish sauce. The sauce's flavor profile will be significantly altered. You might experiment with soy sauce and a touch of Worcestershire sauce, but it won't be the same.
