Fish sauce is the distinctive catch here—it reads as umami depth rather than fishiness—but you'll need to plan a trip to Harris Teeter or Kroger's international aisle to find Red Boat or another quality brand; Food Lion and Walmart carry limited options. The rest of the ingredients are standard pantry and liquor staples, and at roughly $2 to $2.50 per drink, this is genuinely cheap cocktail money. The 5-minute timer is honest if your bottles are open, though you'll want to taste as you go because fish sauce, horseradish, and tabasco ratios vary wildly. This is a two-person brunch or afternoon drink with no leftovers—make it fresh each time—and it rewards a confident hand with the hot sauce and a willingness to dial in umami over tomato sweetness.
