For the beef fillet strips with cassava loaf and coconut-lime crème sauce, first prepare the cassava loaf.
To do this, peel the cassava and boil it in salted water for about 45 minutes until soft. Then finely chop and mash or press through a potato ricer. Mix all ingredients together in a bowl. Shape into loaves and fry out in butter.
For the coconut-lime crème sauce, mix all ingredients together and season to taste.
For the beef tenderloin strips, parcel the beef tenderloin, cut into strips and season. Sear the meat in a frying pan in hot oil for about 2-4 minutes, remove and serve the beef fillet strips with cassava loaf and coconut-lime crème sauce.
