Does such a thing as healthy ice cream exist?

Well it does, and I'm not including sorbet (which is ice without the cream).

This is an "ice cream"? made with just avocados, and it can be eaten as a savoury or as a sweet.

Yes, savoury.

I first discovered savoury ice cream years ago in Italy when my host took me to a restaurant which served parmesan cheese in all shapes and forms.

Aside from wedges, the cheese also came in foams, sauces and, yes, ice cream.

It was rather enjoyable eating a chilled, savoury cream, especially during the summer. You still get all the flavours.

Here, I am employing the same principle, except that there is no dairy in this frozen concoction.

Since avocado is already creamy, I feel there is no need for more creaminess from milk or cream.

This "ice cream"? has a naturally rich, creamy mouth feel and also delivers an element of surprise, for seldom would you find ice cream served in a salad.

I serve it with crab meat - which is an excellent match for avocado - in a salad that also features seaweed, pomelo, cherry tomatoes and Chinese celery.

So, plenty of raw stuff in there.

And eating raw vegetables means that none of the nutrients will be lost through cooking.

To balance the creaminess of the avocado, I also marinate the wakame, a Japanese jelly seaweed often found in a dried form, in a light vinegary dressing.

The pomelo and tomatoes add colour and sweetness, and the celery, a bit of crunch.

I serve this salad primarily for the taste, but it is also rich with superfoods, that is, they are dense with nutrients.

While avocados have a high fat content, they are also packed with nutrients and are a great way to add healthy fat - in particular, omega-3 fatty acids - to your diet.

Avocados also have a higher percentage of protein than other types of fruit and contain many essential vitamins and minerals.

The pomelo and tomatoes can also be described as nutrient-rich.

Pomelo helps to boost the immune system, improve digestion, lower blood pressure, prevent anaemia, boost bone strength and prevent cancer.

Tomatoes are widely known for their outstanding antioxidant content, including, of course, their rich concentration of lycopene, probably the most well known of antioxidants associated with it.

The trio of ingredients makes an excellent combination, both in taste and appearance.

But please do not recite the list of nutrients to your guests when you serve it.

Besides, they will not be listening: They would be too busy concentrating on the flavours found in this super-healthy - sorry, I mean super-delicious - salad.
