Thanks to a colleague, I got to try a Hokkaido Baked Cheese Tart. I liked it. Smooth and creamy, a touch milky. I wished the tart shell was shorter and more crumbly but maybe that's because I had a day after it was bought.
If you bought it fresh off the shelf, it would be lusciously molten; alternatively, you could pop it in the fridge for an hour for it to be chilled and firm.
