Makhani sauce
This rich, creamy sauce is used for the chicken ruby.
- 35g garlic (8-9 cloves)
 - 175ml vegetable oil
 - 20g fresh root ginger
 - 800g chopped tomatoes (fresh or good-quality tinned)
 - 2 bay leaves
 - 6 green cardamom pods
 - 2 black cardamom pods
 - 2 cinnamon sticks
 - 2 tsp fine sea salt
 - 1 ½ tsp deggi mirch chilli powder
 - 30g butter
 - 1 tsp garam masala
 - 20g granulated sugar
 - 1 tbsp runny honey
 - 1 tsp ground cumin
 - 1 tsp dried fenugreek leaves, crushed to a powder between your fingers
 - ½ tsp fresh dill fronds.
 - 80ml double cream
 
- Take 15g garlic and finely dice it. Warm a large saucepan over a medium-high heat and add the oil. Toss in the chopped garlic and fry until light golden brown and slightly crispy, about 7-8 minutes. Remove with a slotted spoon and drain on kitchen paper.
 - Grate the remaining garlic and the ginger to a fine paste on a microplane, or grind using a pestle and mortar.
 - Using a blender, blitz the chopped tomatoes to a fine consistency.
 - Place the saucepan containing the oil back over a medium-high heat and add the bay leaves, green and black cardamom pods and the cinnamon sticks. Let them crackle for 1 minute, stirring regularly.
 - Turn the heat down and add the garlic and ginger paste. Cook for 5 minutes, allowing the paste to brown but not burn.
 - Add the tomatoes, salt and chilli powder to the pan. Bring to a rapid simmer and cook until reduced by half, stirring regularly so that it doesn't catch. This should take about 30 minutes.
 - Add the butter and simmer for a further 5 minutes.
 - Add the garam masala, sugar, honey, cumin, crispy garlic, dried fenugreek and fresh dill fronds and cook for a further 15 minutes.
 - If the sauce is to be used straight away, add the cream and simmer gently for 5 minutes; it is then ready to use. If not using immediately, alow to cool, cover and refrigerate; add the cream when you reheat the sauce to assemble your dish.
