I've just seen this Guardian article about eating alone, and it mentions about a couple of food sharing websites.
I looked at shareyourmeal.co.uk, and it's a great idea! You put on the site what you're cooking, and if someone local wants some they get in touch, and pay you for the ingredients.
I love cooking, but it always feels a bit too much effort just to cook for one (and I'm never keen on bulk cooking / freezing), so this seems ideal.
But then I wondered - although I'd only be charging for the other person's share of ingredients, would there be any additional responsibility re: food hygiene / public liability etc? Would it matter how often I did it?
