Cut the meat. Cut off the ends of the lemongrass stems and use only the juicy parts. Cut the stems into approximately the same size pieces and then chop finely with the mixer or a knife. Mix the salt, pepper, sugar, fish sauce and garlic. Add the meat, ginger and finely chopped lemongrass. Stir the ingredients by hand so that the marinade spreads well. Put in the refrigerator for at least 2 hours.
Prepare the sauce. Dissolve the sugar and salt in the water. Add the fish sauce, garlic and chilli. First add the juice of 2 limes, mix and taste if there is more lime juice to go with it. Set aside. You can prepare the sauce in advance and store it in the refrigerator. The sauce then stays good for 1 week.
