There are many recipe sites that allow you to tap in a list of ingredients and will then find you meals for you to cook. This google search goes one further, it looks at the items you enter, and searches the web for recipe ideas, not just one site.
Sadly, a day post the great event and I find myself with haggis, neeps, and tatties that still need using, no problem with ‘Cookin' With Google’, recipes are found for me.
With financial depression biting this could be a useful site to make a meal from those items at the back of the fridge (If you can identify as to what they are!)
But for unexpected guests ‘you’ll have had your tea’ is still the cheapest form of greeting!
