Remove skillet from stove to cool down slightly, turn down to medium.

Return skillet to stove, heat sesame oil.

Add garlic, ginger and chilli flakes. Cook until garlic turns golden.

Add water, then Sriracha, soy sauce and sugar, Stir, increase heat to medium high, and let it simmer for 3 minutes or until the sauce starts to thicken to a thin syrup consistency.

Return prawns into skillet and toss to coat in sauce and reheat, and cook for 1 - 2 minutes until sauce is reduced and coats the prawns nicely.

Garnish with sesame seeds, fresh chilli and shallots if desired. Serve with rice to soak up the awesome sauce! (Low carb, low cal option, try Cauliflower Rice) Side salad suggestions in post.
