Sounds like a Hawaii style Crack seed store special. We used to see big jars on roofs, not so much any more. So cool you found her actual recipe card and used it here. I admire your element usage. The fancy frame corner, stitching, and beautiful color combo especially.
How awesome that you were able to find your grandmother's handwritten recipe. I also really like the journaling that you've done on your page to go along with the recipe.
