Marinate the meat with the sesame oil and soy sauce for 1 hour, stirring occasionally.
Heat the neutral oil in a pan, fry the meat and onion, remove from the pan. Lightly fry the curry paste in the roasting set, stir in the coconut milk with a whisk, simmer. Then add the peppers, the meat, the lemon leaves and the lemongrass, fish sauce, chilli peppers and the bamboo shoots and simmer on a low flame for 10 minutes (with the lid slightly open), add vegetable broth or water if you like, when the sauce is added should be thick.
