It sounds like your friend would appreciate a gift certificate to a local culinary school that offers traditional food and drink making classes. Personalized cooking utensils or a cookbook featuring traditional recipes from their favorite cultural cuisine could also be a thoughtful gift. Another idea would be to create a handmade recipe book with traditional family recipes contributed by the couple's loved ones. This could be a meaningful keepsake for them to treasure and pass down through generations.
