THIS EXPERIMENT MUST BE CARRIED OUT IN HYGIENIC CONDITIONS IN THE HOME ECONOMICS DEPARTMENT (APPLIED CONSUMER SCIENCE DEPARTMENT).
\nUSE FRESH INGREDIENTS FROM THE SUPERMARKET, NOT MATERIAL THAT HAS BEEN STORED IN CHEMICAL CUPBOARDS.
\nUSE APPROPRIATE PERSONAL PROTECTIVE EQUIPMENT WHEN USING LIQUID NITROGEN<\/p>\n
1. You don\u2019t need a strictly measured recipe but here\u2019s a guideline:
\nPour 600mL of cream and the same amount of milk into a large metal mixing bowl.
\nAdd castor sugar to taste (probably quite a large amount, 1-2 cups?) and stir with a wooden spoon to dissolve as much as possible.
\nAdd a splash of vanilla essence (or some recipes use chocolate\/strawberry topping to taste).
\nPour in some liquid nitrogen \u2013 we used a few hundred mL over two or three pours, using a stainless steel thermos filled from our Dewar \u2013 and stir vigorously straight away. Don\u2019t add it all at once or parts of it will freeze too hard.
\nOnce made it can melt quickly so eat fast!
\n2. Generally, we use the cheat\u2019s method because it\u2019s much cheaper and easier.
\n2L vanilla ice cream (Buy the vanilla ice cream, let it melt and transfer to large metal bowl.)
\n1 cup Smarties
\n250ml Choc sauce
\nLarge flat wooden spoon
\n1L liquid nitrogen
\nMix choc sauce into ice cream.
\nSlowly add liquid nitrogen whilst stirring with wooden spoon adding the smarties as it begins to thicken.
\nContinue adding liquid nitrogen until completely frozen.
\nSpoon into small cups.
\n(Making up an ice cream recipe using cream, etc would just require following the recipe, until it is ready for freezer, then using the liquid nitrogen instead.)
\nIf there is a little nitrogen left over, staff can have a treat with a sorbet. \u2013melt 1 cup sugar in 1 cup water in microwave. Mash up a punnet of strawberries or other fruit. Mix, then and add liquid nitrogen.
\n3. Buy some tubs of cream (approx 2 tubs for about 20 people for a spoon size taste each) put them in a stainless steel bowl. Add flavouring if desired, we use strawberry, pour in liquid nitrogen and start whisking taking all safety precautions such as goggles, mitts, etc. It doesn\u2019t happen instantly but takes at least 10 minutes and the resultant ice cream tastes different and doesn\u2019t have the same texture as the commercial product, however the kids love making it.
\n4. Allow 2 litres per class to fully melt (takes a few hours).
\nThen pour in the liquid nitrogen while stirring icecream. Kids will love it!
\n5. Buy a tub of ice cream and allow it to melt, or:
\nPrepare the night before:
\nMilk 300ml
\nChocolate sauce
\n3 eggs lightly beaten
\n50g caster sugar
\nEvaporated milk 410ml
\nCream 300ml
\nHeat milk, chocolate, eggs and sugar in double saucepan, stirring constantly until mixture coats the back of a spoon.
\nCool overnight.
\nJust before adding nitrogen:
\nWhisk evaporated milk and add. Whip cream and add.
\nMix in nitrogen as quickly as possible while the mixture is still well aerated.
\nNote: the volume of liquid nitrogen is approximately the same as the volume of the ice cream mixture (1 litre)<\/p>\n","protected":false},"excerpt":{"rendered":"
