The engineers at Columbia University must have sweet tooths… They’ve developed a method to make fully baked desserts using cutting-edge technology. Testing it out with a 7-ingredient vegan cheesecake recipe, they used lasers and 3D-printing machines to assemble and cook the dessert. And while they might have had a hankering for cheesecake, it was actually about developing practical uses for 3D printing to create food – and the use of lasers is a significant development because of the need for heat in producing many food items. That might sound a bit like sucking the joy out of baked goods, but consider this…  Every slice could be customised to include different flavours and textures. Dr Jonathan Blutinger says “that’s a really cool part of the printing process that you can actually localise flavours” so that every bite is different. You know what’s really cool? Having a job where your focus is developing cool ways to make cheesecakes…
