I like the idea of saving recipes online. What I wish existed was something which would let me take a photo of a dish I’m eating and tell me how to replicate it at home. There’s been so many times I’ve eaten something at a restaurant or someone’s house and want to make it at home, but it’s inconvenient to ask for the recipe.
