How about a Brazilian cookery book like "The Brazilian Kitchen" by Leticia Moreinos Schwartz? It contains recipes for traditional Brazilian dishes that your mom can try out at home. You could also throw in a set of Brazilian spice blends, such as "Tempero Baiano" or "Pimenta Biquinho," so that she can get the authentic tastes right. Additionally, you could gift her a meal voucher to a popular Brazilian restaurant in your area, or a cooking class where she can learn to make Brazilian delicacies herself.
Or you can get her a star map with an important date you share.
