A Trifle Deffo!

What makes a trifle? Well ask Sian and a trifle can be one of numerous things. I believe a trifle consists of jelly, cream, custard, fruit and sponge. This is the basis of my dislike of trifle...."well dont have the sponge in it then" says Sian. But then it's not a trifle? or is it? It has to be called something else, if it is just jelly, and cream and custard...it's not a trifle, the trifle must consist of fruit, and also have the soggy sponge in the bottom.....y u k.
