Ponzu sauce is the real obstacle here: Harris Teeter and Kroger carry it in their Asian sections, but Food Lion and ALDI do not stock it reliably, forcing a second stop for most readers in Charlotte. The other ingredients—fresh ginger, scallion, mirin, and sesame oil—are available at all major chains, though mirin may need a Kroger or Harris Teeter Asian aisle trip if your nearest store keeps it only in specialty sections. At roughly $8–10 total for a two-serving sauce with ponzu as the anchor expense, the per-serving cost climbs fast if you're buying it for the first time. The five-minute time is honest, but this is a condiment, not a meal: budget for what you are dipping and plan to use every drop within a week, as the refrigerated shelf life is shorter than most pantry staples.
