1-1.5g per person of any hash you got, blacks melt easier (this is my dosage, newbies scale down)
3 large teaspoons of hot chocolate powder (Cadburys etc), not the instant sachets with dried milk, proper stuff in a tin, the higher the fat content the better
1/2 pint of full fat milk (dont use semi skimmed), again high fat works best
Crumble or break up by hand the hash into as small a pieces as poss (with Morrocan I put it in the oven for a few minutes at 150 degrees C to soften it, then it crumbles between your fingers easily, dont over cook it though),
Put the milk in a non stick saucepan, warm up but dont boil it, add the hot chocolate and the crumbled hash, stir non stop for several minutes at moderate to high heat (still dont boil it) with wooden spoon and work the hash at the bottom of the pan to stop it lumping up, bring to the boil after several minutes of this, as soon as it boils pour into cup, there will be a mulch at the bottom of the pan, you can strain this to get more of the good stuff out if you want.....Top with whipped cream (more fat to help you absorb the thc
