Step 1: Place all ingredients into a blender.
Step 2: Blend until orangeish and foaming.
Step 3: Pour into the pint glass.
Step 4: Place in the straw and ice.
Step 5: Make a small slit in the slice of apple.
Step 6: Stick on the side of the glass.
Step 7: Top tip: To keep people sober, add a little bit of cider in place of apple juice (eg 100ml of cider and only 400ml of apple juice). It tastes alcoholic, but you need to have lots and lots of pints of it to get drunk.
