How about a Caribbean cookbook that they can use to cook up their favorite dishes? There are plenty of great options available on Amazon like "Caribbean Potluck" by Suzanne and Michelle Rousseau or "The Essential Caribbean Cookbook" by Heather Thomas.
Another great option would be to sign them up for a Caribbean cooking class. This would give them hands-on experience to learn new recipes and techniques from a professional chef. You can search for cooking classes online, or even check out cooking schools in your area.
If your son enjoys traveling, you could also consider booking a trip to the Caribbean. This would give them the opportunity to not only taste authentic Caribbean food but experience the culture and atmosphere of the region as well.
