Let it know what you fancy, it'll tell you what to make
I get this problem a lot, I'm hungry, I've kinda got an idea what I fancy, but I'm not quite sure what to make.
As is always the case, there's a website out there that has just the answer you're looking for. In this particularly scenario, that website is CookThink.com.
CookThink's website allows users to find exactly what they're craving by letting them search for recipes by a combination of ingredients, dish types, cuisines and moods.
On the website, you simply enter up to eight tags describing what you crave and it'll find a related recipe. To test the service, I entered "chicken" and "mushroom" and had recommended a recipe, complete with cooking instructions, for "Chicken Ragout with Tomatoes, Herbs And Mushrooms". Handy!
The CookThink website is still in beta form, so expect the service to improve over time. Nonetheless, it's a clever yet useful idea.
