Soak bamboo skewers for several hours in warm water prior to threading the beef onto them, to prevent burning.
Cut Beef into thin strips, mix all other ingredients together in a a large bowl. Place the beef strips in the bowl with the marinade and leave for some time ( at least one hour, maybe even a day ).
Thread Beef onto skewers and cook over hot coals ( Grilling works just as well ).
Take remaining marinade and pour into a small saucepan, with a few tablespoons of peanut butter, add water, chilli sauce & lemmon juice to taste. Cook over a low heat until sauce thickens.
Serve satays with rice and peanut sauce.
