Guess the weight of the cake

I donated a cake for a 'Guess the weight of the cake' competition recently, and was surprised at the result. Four people (out of 40) correctly guessed the weight, measured to the nearest pound. Considering that I guessed wrong myself, I was duly impressed. No pictures unfortunatley as I forgot, but I made a fruit cake and arranged almonds in a starburst pattern on the top. I was hoping to make it more decorative, as fruit cakes, while nice to eat, don't look spectacular. I kept it undecorated as it would be more difficult to judge it by sight covered in marzipan and icing. Some people did pick it up and hold it, making me panic as it was still wrapped in the greaseproof paper (to keep it moist) and wasn't secured to the cake board. It prpably would have survived a fall, but unless there were no witnesses I couldn't pick it up and put it back on :)

The only problem with things like that are I have a nagging worry that I've put curry instead of mixed spice, or something similar, since I won't get to 'check' it myself. I haven't heard anything back, so fingers crossed!

Oh and just in case you ever need to know, a 9 in fruit cake weighs 4 lb 8 oz.
