Smoothies.

Thick, pockmarked, gritty, gravelly, peppery. Spicy.

Cinnamon Rush.

Your starter for ten, sir. One for the rookie, the sweet-toothed trooper.

1 Teaspoon cinnamon
1 pint instant-milk; from powder
1 old, bruised, battered banana, chopped
4 heaped tablespoons caster sugar.

Perhaps could be enjoyed on one of these cold, wet, summer mornings.

Black Death.

1 Old banana, bruised
Dash cinnamon
As much sugar as you see fit
3 Ice cubes
Milk
Handful sultanas.

Add a good tablespoon of tar black treacle once blended.

Blend. Note brown, muddy, viscous texture. Chewy, almost.
Watch out for the lump of tar hiding at the bottom of the glass, you wouldn't want that to get the better of you.
Not one for the intellectual, or under 12's.

Grubby Potato Freedom-Blaster Superior.

2 Potatoes, dirty as you can, chopped. Skins on.
Sugar.
Pinapple, 1 tin.
Anything else you can find on the floor; for example, toenails, dust, dog hair, etc., etc.

Should probably come served with a disclaimer. Dangerous, to say the least. You'd better be ready when this shit goes down.
