The day before, peel garlic and ginger and dice finely. Wash mint and half of the coriander, shake dry and chop. Mix garlic, ginger, chopped herbs, 3 tbsp. oil, 1 tbsp. cumin, 1 tsp. salt, Garam Masala and 150 g yoghurt.
Wash the meat, dab dry, dice and mix with the yoghurt marinade in a large flat casserole dish. Cover and leave to stand overnight in the refrigerator.
Preheat oven the next day (electric cooker: 200 °C/circulating air: 175 °C/gas: level 3). Put the meat in the form in the oven, roast for 35-40 minutes.
In the meantime peel the banana and mash it into pulp with a fork. Mix 3 tablespoons of oil, tomatoes and juice, 150 g yoghurt and banana, while crushing the tomatoes. Bring to the boil while stirring, cover and simmer at low heat for 8-10 minutes.
Add almonds, approx. 1 teaspoon salt and coconut milk, bring to the boil and continue to simmer for 5 minutes. Season with 1⁄2 tbsp. cumin, turmeric, Tandoori Masala and chili. Wash the rest of the coriander, shake dry and chop.
