There's simple rules regarding food in my house...
1- Can it be bought it Asda/Tesco/Co-op, if the answers no you have to travel to outer mongolia for a herb which only grows on the 2nd tuesday of ever lunar month, forget it.
2- Will the entire family eat it including any leftovers that end up the dogs way? if no, again, its a none starter.
3- most importantly, is it cheap? If I have to remortgage my house just to buy the 10 thousand ingedients (which incidently you'd never use again), then again- we'll stick to egg and chips thank you very much.
