How about a global cuisine cookbook that contains recipes from different parts of the world? There are many cookbooks available that explore the flavors and cultures of various regions. Another idea is to give your friend a spice set or a set of unique spices from different countries, so they can try different culinary experiences at home. You could also get them a subscription to a monthly international food box that sends unique and delicious treats from around the world. Finally, you could organize a cooking class for them and a group of mutual friends to explore the flavors of a specific cuisine together.
