I also love the smell of fresh coffee (plunger kind, not instant)
Apple stroodles that I make for Mistress
Okonomiyaki, a Japanese pancake thing that I cook sometimes
This bubblegum scented perfume that my Mistress wears sometimes, when I'm good. (Bubblegum not nearly as gross as I thought, quite the opposite in fact)

But MOST of all,
I love the smell when I am worshiping my Mistress.
