The best and delicious sausage of vegetables and meats is made with butter. But be careful. When the butter melts, we do not immediately put the vegetables in. Butter contains 16% moisture. As it melts it starts and fills and stays at the temperature of 100 degrees Celsius until all the water evaporates. When this is done, it continues to increase its temperature and this is the right time to start putting the vegetables in our pan and in this way we have the best results.
