that is too cool. Did you do any cooking with grandpa?? My Grandma and grandpa did not own any kind of grill ever, can you imagine??
I'm a smoker/BBQ horder and view them as tools that are meant to be used.. If you have memories of cooking with grandpa, what a great way to remember him. Either way, I am sorry for your loss. But what a great brownie to remind you of him, thank you for sharing.
