How about giving her a Thai cooking class? It can be a fun and unique way to not only enjoy her love for Thai cuisine but also to spend quality time together as a couple. Alternatively, you may want to give her a Thai cookbook that she can use to try out new Thai recipes at home. You could also consider booking a reservation at a high-end Thai restaurant for a romantic dinner. Additionally, you could consider purchasing her a set of Thai-inspired kitchen tools or decor, like a mortar and pestle, spice jars or hangings.
Or you can get her a star map with the date of your anniversary.
