The fruit slush looked a bit like one of our favourites, only I think ours is healthier. It would taste just as good, if not better.
We use frozen fruit if possible. Frozen banana, frozen mango, frozen passionfruit (but you'd need to strain out the seeds), frozen pineapple (also need to strain - it can be a bit fibrous) and frozen berries. Raspberries go a very long way and make it VERY red, with just a few. You put whatever fruit you want, but try to include at least one banana, into the blender. If you want it completely frozen, add nothing else. And be prepared for an ice cream headache/brain freeze!
Or, you can use 50/50 juice and water (about half a cup total for one person) with equal volume fruit. THAT is drinkable through a straw without waiting for it to half-melt.
We had the frozen fruit version at a country farmer's market in tropical Queensland. It cost a bomb and tasted marvellous. You don't need to add any sugar if you've got a ripe banana in it.
The liquid version, I was having it for breakfast every day for several years.
If you want a party atmosphere, add a paper umbrella.
Or there's the milk version - very naughty in taste, actually quite healthy.
one raw egg, a cup of milk, a banana if you want, then drinking chocolate with optional malted milk powder. Blend the lot, enjoy. Very rich, very filling. Loaded with protein, fibre and potassium (those two from the banana) and a few vital amino acids. Vitamin A from the egg.
Or a healthier version - leave out the chocolate and malt, use the banana for sure, sweeten with a bit of honey if you want. Add a dash of vanilla essence for a richer flavour.
The thing with those, you can make some for everybody so he doesn't feel like he's on some 'stupid special diet'.
