This is an easy crowd pleaser. I have been making it for years. This is my first attempt to write it down (I may come back and make some edits to the "dressing". I have always just kind of mixed things together. I have found that using some authentic ingredients does make it stand out. Fish Sauce and sriracha hot sauce are availabe in the Asian section of most supermarket today. White pepper is hit or miss. Spice stores and many ethnic grocery stores carry it. The French use it in white sauces so you get the pepper flavor, but you do not the specs.
This is not an exacting recipe. If you want is spicier add more hot sauce. If not, use less. More tart add vinegar, etc. Add grilled chicken or cooked shrimp and make it a meal.
Prep time is about 30 minutes. It does need to chill 2 hours before serving.
