STEP 5: Cover the mixture and set it aside for a few minutes.

STEP 6: Get a clean frying pan, turn on your cooker, and put it on it. Add your vegetable oil and add little sliced onions into the oil. Allow frying for 3 minutes.

STEP 7: Make the cassava mixture round or flat and add to the frying pan. Allow frying for 5 minutes.

STEP 8: Get your frying spoon, flip it to the other side, and let it fry until it turns golden brown.

STEP 9: Use the frying spoon to get the fried Kosan Rogo into a sieve.

How to Make Kosan Rogo (with Fresh Cassava)

Equipment Needed

Frying pan
Mortar and pestle
Blender or grater
Frying spoon
Sieving container or colander


3 tubers of cassava
Fresh pepper and onions (ground)
Spices (curry, thyme, and garlic)
Vegetable oil for frying
Seasoning cubes and salt to taste.

Procedures for Making Wainan Rogo with Fresh Cassava

STEP 1: Put the cassava tubers in a clean container and add enough water to soak for an hour.

STEP 2: When well soaked, peel the cassava with a knife. Just be careful not to injure yourself.

STEP 3: Cut the peeled cassava into small chunks, wash properly and keep them aside.

STEP 4: Here, you could either pound the chunks using a mortar and pestle, or you could just use a grater. Any one of the two will do a good job. However, mortar and pestle will yield a faster result.

STEP 5: After pounding or grating, pour the content into a clean bowl and add ground onions and pepper. Mix them very well.

STEP 6: Grind it with a blender and sieve, and squeeze out the water.

STEP 7: Put it into an empty bowl and then add the seasoning cubes, spices, salt to taste, and sliced onions. Mix them very well until well combined.

STEP 8: Fetch the mixed cassava, pour it on your palm and make a small ball. Use your two palms to flatten it. Repeat the same process until all of the dough or mixture is exhausted.

STEP 9: Put on your cooker and put a clean frying pan on it. Pour your vegetable oil and a few slices of onions into it. Allow frying for 3 minutes.

STEP 10: Add STEP 8 one by one into the frying pan (just enough to fit the oil in the pan). Allow frying for 5 minutes until it turns golden brown, then flip them over so that the other sides will fry.

STEP 11: Repeat the above process until all contents in STEP 8 are exhausted.

STEP 12: Use a spoon to get the fried Kosan Rogo into a sieve.

STEP 13: Scoop the fried pieces onto a clean bowl and allow them to cool.

STEP 14: Ta-da! You are done!

Preferably, prepare just enough for present consumption as you have seen, Dan na rogo is easy to make.
