Step 1

Heat the vegetable oil in a small saucepan over high heat. Add spring onion, sliced chilli, if using, and garlic and cook, stirring, for 1 min or until fragrant. Reduce heat to low. Add the tamari or soy sauce and sugar. Cook, stirring, for 3 mins or until the sugar dissolves. Simmer for 5 mins or until the sauce thickens. Stir in sesame oil.

Step 2

Place the sea salt, peppercorns and chilli flakes, if using, in a mortar and pound with a pestle until finely crushed (alternatively, use a spice grinder). Place in a medium bowl with the rice flour and stir to combine. Add the tofu to the rice flour mixture and toss to coat, shaking off excess.

Step 3

Add enough oil to a medium frying pan to come 1cm up the side. Heat over medium heat. Cook the tofu, in 2 batches, turning occasionally, for 5 mins or until golden brown. Transfer to a plate lined with paper towel.

Step 4

Arrange the tofu on a serving platter. Serve with the sauce.
