A box of four Caneles de Ginza by Boul'Mich sells for $10 at j.Sweets, the pastry shop inside Mitsuwa. Bonbon size, they look lovely with dark brown, waxy exteriors. The insides are quite wet and doughy, neither custardy nor cake-like, and are chewy almost like mochi. The flavor has a weird woody, rancid aftertaste. Not something I'd want to taste again. Here are some photos from Japanese language blogs.
