I've been looking for these two items for a while now. They are NOT meant to be used in the same dish, so don't worry. Haha.
Guava paste is for a dessert of Puff Pastry stuffed with Guava Paste and Gouda Cheese.....YUMMY.
And the Vienna Sausages are for hot dogs as I visited Chicago in October and now want to try and re-create the Chicago Dog. I remember seeing Vienna Sausages in grocery stores when I was a kid, but can't find them anywhere now.
Thanks for your help!
