In Thailand, curry pastes are made in a large mortar by grinding. If you don't own a mortar, you can put the ingredients in a grinder and press a button.
Add a generous amount of rapeseed oil to the bottom.
Rinse and dry the chicken meat with a paper towel. Cut into strips.
Wash the bell peppers and cherry tomatoes. Cut the tomatoes in half and chop the bell peppers into strips. Spring onion also into small pieces.
This is where things start to happen fast!
Throw a slice of chicken into the wok. If it starts to rattle then the wok is hot enough.
Fry the chicken strips until brown quickly. No need to cook through.
Add 1 tsp red curry paste, 1 tsp coconut milk (creamy part), 1 tbsp sugar and fish sauce to chicken and quickly swirl to "caramelize" the chicken.
Add the prepared vegetables immediately after that and fry a minute.
Add the remaining curry paste (to taste), sugars and coconut milk. Bring to the boil and the red curry is ready.
