The Evil That Is Chocolate Pudding

Today, something awful happened. Whilst making instant noodles and toast for dinner, I stumbled upon a huge tub of Cadbury's Cocoa Powder...that is when the evil began.
I decided that I should take a look on Google to see what I (an extremely novice cook) could put together.
I found this recipe for 'Finnish Chocolate Pudding'
500ml Milk
2 Tbsp Sugar
0.5 Tsp Salt
1 Tbsp Cocoa Powder
80g Flour

I followed the instructions to simmer the milk on the hob, then add the other ingredients. Keep cooking and stirring until the mixture is thick.

Anyhow.. I did it, and it was lumpy, I figured, I didn't mix it in enough or something.. but it tasted ok, so I tried again...this time, it tasted like I'd put too much flour in it..so...I tried AGAIN! Third time lucky...right? So I mixed the ingredients, cooked, stirred & simmered until ready.
It looked gorgeous, it smelt heavenly... so I tasted it, it was all right, but not as nice as I'd hoped, so I added some sugar while it was still pretty hot, and stirred it in, I was it melting and thought to myself how delicious it was going to be.
I left it to cool down a little so I could taste it properly, it was too hot to go into the fridge, so I put a tea-towel over the top and let it rest.
20 Minutes later... I take the tea-towel off the bowl, grab a dessert spoon and dig in.
I don't know whether it was my cooking, or the recipe, or those darn Fins and their demented taste-buds...but whatever it was, made me spit out the so-called 'Chocolate Pudding' and throw it into the bin.
I have made myself a promise, that I'm not going to cook anything for the foreseeable future.
Now I have nothing to eat, and a tummy with icky pudding in it!

If you have any ideas.. please let me know..
