One idea could be to cook her a special anniversary dinner featuring carrot and potato dishes that she would love. You can search for unique and delicious recipes that include these ingredients and make a romantic evening out of it. You could also consider getting her a recipe book that specifically caters to dishes made with carrots and potatoes, so she can continue cooking them on her own time. Another idea could be to get her a gardening kit with carrot and potato seeds, so she can start planting her own vegetables and keeping them as a hobby. This will not just fulfill her interest in carrot and potatoes, but also give a sense of journey that would grow over time.
Or you can get her a star map with the date of your anniversary.
