First step: The first thing we are going to do is to put the butter on low heat. After it is completely melted, we are going to put little by little the flour and mix at the same time without stopping to avoid lumps. Then add the oil and the result will be a kind of dough, as we can see in the picture. After both ingredients are ready, we can start the other steps.
Second step: The next step to follow is to heat the water until it is lukewarm and we will add the seasoning cube and let it dissolve in the water. Then we will add the rest of the seasoning, salt, pepper, soy, and parsley, we will mix them until we get a broth and we will add over low heat to the mixture little by little without stopping to mix with a spoon, since it is easy to create lumps and we will stop mixing when our sauce is ready having a creamy result, but thick enough to accompany our food.
