A beloved British takeaway classic of velvety, mild curry sauce infused with warming spices, sweet apple purée, and garlic, perfect for pouring over hot chunky chips.
Sautéing Aromatics: Heat oil in a saucepan over medium heat. Add the grated onion and minced garlic, sautéing gently for 4-5 minutes until softened and translucent.
Spicing & Roux: Stir in the curry powder, turmeric, cumin, ginger, and plain flour. Cook for 1-2 minutes, stirring continuously to form an aromatic spiced paste.
Simmering: Gradually whisk in the stock to prevent lumps. Add the apple sauce, soy sauce, and sugar. Bring to a gentle boil, then simmer on low heat for 10-12 minutes until thickened and glossy.
Serving: Blend until completely silky smooth if desired. Season with salt and pepper, and pour generously over piping hot chips.
