What did the Europeans learn from the Turks and other Muslim countries in Asia?

For a long period of time, European states lived cut off from the east. The same situation was there. That is, there were practically no connections between the West and the East. True, the situation changed a lot when the Crusades began, which marked the beginning of the development of sea trade between Western and Eastern countries. This led to the fact that Europeans borrowed the tradition of tea drinking and coffee drinking. In addition, gunpowder was borrowed, as well as Arabic numerals.
