I made it! My husband and I love eating perkedel kentang. It is a name of Indonesian traditional food made from potatoes.For a long time, I was so curious how people can make it so delicious and tasty. I have asked some friends of mine how to cook it. Then, this morning, I thought, why didn't I use internet access and find it how. So I decided looking for some recipes. I found some then finding that I had done one little mistakes in doing it. The potatoes should be fried, not cooked with water (rebus in Indonesia, I don't know how to say rebus in English). It was just a little mistake but influencing the whole recipe and and taste. Today I made it. My perkedel kentang do not crumbled anymore when I fried them. My husband was so surprised and congratulate me for my effort.^_^
