Ingredients
20 long red chillies (about 250 grams), deseeded and sliced 

2 garlic cloves, peeled and sliced
20 grams ginger (about 4-cm piece), peeled and sliced
2 small banana shallots or 4 Thai shallots, peeled and sliced

180 grams cherry tomatoes
1 teaspoon tamarind paste (or 1 teaspoon lime juice mixed with 1 teaspoon brown sugar)

1/2 teaspoon palm sugar or brown sugar
Instructions
  1. Place the chillies, garlic, ginger, shallots and tomatoes in a food processor and blend to a semi-fine paste, retaining a little texture.
  2. Place a frying pan over a medium heat and add 4 tablespoons of oil. Add the paste to the pan and cook, stirring continuously, for 10–15 minutes or until the sambal darkens, is fragrant and reduces to a thick consistency. Season with the tamarind paste, sugar, salt and pepper. Leave to cool.
