Prepare a fryer or large stock pot filled 1/3 with oil at 375 degrees. First, blanch the taro, sweet potatoes and potatoes in the fryer for about 6 minutes until they are soft and slightly tan. Drain on paper towels and set aside. In a mixing bowl, whisk together the flour, white pepper, oil and sesame seeds. Slowly add the beer while whisking. The batter should resemble pancake batter. Dip each piece of fish in the batter and gently drop in the fryer. Fry until golden brown, about 4 to 5 minutes. Take out with spider or tongs and drain on paper towels. Immediately season with fleur de sel. Turn fryer up to 450 degrees and fry the fish a second time, until golden brown, about 3 to 4 minutes. Drain on paper towels and season with seasoned salt.
In a food processor, add the yolks and garlic and puree at high speed. Slowly drizzle in the oil until in comes together (emulsifies). Then add the oil a little quicker until you have a thick mayonnaise. Add the 2 vinegars and season. The aioli will be much lighter and thinner once the vinegars are added. Fold in the chives.
Plating: Using an Asian newspaper lined with parchment, roll a large cone and fill with fries. Top off with fish and serve the aioli on the side in a small decorative dish. Garnish with chives.
Beverage: Very cold English Bitter
