Outstanding recipe! My husband is from The Netherlands and he is also Indonesian. During our last family reunion the family made us a wonderful Indonesian meal and the Sate was my favorite, his too. I really like the kecap manis and the sambal oelek. These are common ingredients in Dutch supermarkets as Indonesians are historically a part of the Dutch community. I recommend this recipe as it is very authentic. I also recommend preparing a peanut sauce to go with it as I have never had it without, whether in a restaurant or at my in-law's home. The peanut sauce should be specifically an Indonesian sauce as it is a wonderful flavor of sweet and spicy. It is much different than Thai Sate and peanut sauce, it's thicker for one. Just my opinion but after having the Indonesian version at my family's home I haven't ordered the Thai version since. My husband is very lucky to have grown up eating this type of food!
