In a chilled bowl, mix tuna, hot pepper sauce, chives, olive oil, salt and pepper together. Using a PVC mold or empty can, build a parfait alternating layers with tuna and tobiko, then tuna and caviar. Top with whipped cream and garnish with chive points. Drizzle plate with vinaigrette.
Mix all together. Should not be emulsified but a broken vinaigrette. Check for seasoning.
