Heston Blumenthal/ In Search of Perfection /Raspberry sorbet

Heston Blumenthal/ In Search of Perfection /Raspberry sorbet
Serves 4

Preparation time 2 hours, including freezing time
Cooking time not applicable
Ingredients * 750g/1¼ pints frozen organic raspberries * 85g/3oz fructose * 2 tsp vodka * crushed dry ice * white chocolate tubes, to serve

Method 1. Thoroughly thaw the raspberries, then purée them in a food processor or blender. Pass the purée through a coarse sieve to remove the seeds.
2. Weigh out 625g/1lb 6¼oz of the purée and add this to a bowl containing the fructose and vodka. Stir until the fructose has dissolved. At this point the sorbet base can be refrigerated until needed. Reserve the extra purée for finishing the dish.
3. To prepare the frozen sorbet, pour the raspberry base into the bowl of a food mixer and, using the paddle attachment, begin mixing it at a slow speed. Crush the dry ice by wrapping it in a tea towel and beating it with a rolling pin (watch your fingers!). Slowly add spoonfuls of the crushed dry ice. Continue mixing and adding dry ice a little at a time until the sorbet has frozen.
4. Scrape the sorbet into a piping bag and place in the freezer for about 20 minutes to harden slightly.
5. Use the piping bag to inject the sorbet into white chocolate tubes placed upright on a tray. Place the tray in the freezer for the sorbet to harden. Any extra sorbet can be kept in the freezer in a sealed container. The remaining purée can be used as decoration.

Where can you get dry ice? I only have wet ice...

[jamsbruno1]

@dark0fday use a hair dryer to dry them

[retrotw]

@meadslosh that is cool...honestly...lol im never a good science guy...haven't learnt any science since junior high school or intermediate....depends where u r from

[meadslosh]

@retrotw Yes, dry ice is much too cold to put directly into your mouth, as it will freeze the water in the cells in your tongue, gums, etc. But for the same reason, it makes it an ideal way to freeze ice cream, which has a much lower freezing point than pure water. When the dry ice touches the fruit puree, the transfer of energy from the fruit to the dry ice causes the puree to freeze and the dry ice to sublimate, or go directly from solid to gaseous state. It's science, and it works.

never knew dry ice can be eaten...i thought it burns...

[lycheesack]

@jamsbruno1 I hang mine on the cloths line in my backyard, careful not to put it near your undergarments or you'll be in big dodo.

@dark0fday you can pretty much get dry ice at any chemical selling store. Just check the web, you'll find it.

@dark0fday

A number of possible sources for you: (as I don't know which country you are in)

1) Any major ice cream manufacturer (e.g. Streets ice cream)

2) Any major supplier of industrial gases (e.g. Air Liquide, BOC Gases)

3) A specialised shop selling dry ice and "wet" ice (e.g. Fiegerts Ice in Australia)

Other things to note:

1) You should look for the pelletised form, rather than day blocks (or you will have to smash it up yourself like Heston).

2) Make sure it is FOOD SAFE.

Good Luck!

@dark0fday

I dont know which country you are asking this question from but here are two possible sources:

1) Any Ice Cream company (e.g. Streets Ice Cream)

2) Any Company that provides industrial Gases (i.e. Air Liquide, BOC Gases)

3) Highly specialised shops that sell only dry ice or other frozen product (in Australia we have one called Fiegerts Ice).

You should be looking for dry ice "pellet" and not block form. Make sure that you also ask for FOOD SAFE dry ice.

Good luck!
