Contrasting textures and flavours is a wonderful way to keep the palate excited! I'm so on board with the crispy, creamy, savory combo you've described - deep-fried tempura veggies with that delicious crunch are one of my all-time favorites!
Some of the best meals are those adventurous ones that play with our senses and it seems like you've thought of some great contrasting elements. The pear with wasabi and ginger would be a brilliant refreshing contrast, and who doesn't love a good spicy kick?
It's definitely making me hungry thinking about all the delicious possibilities! Bring on the taste bud tantalising treats!
