Berry Cool Ice Cream

Berry Cool Ice Cream

 

Everyone loves a good science demo, right? A good explosion, crazy bubbles flying out of tubes, weird and creepy dissections. I may be a bit biased when it comes to the whole science being fun thing, but I can promise you that this will be the best tasting experiment you’ll ever ace!

 

I’m going to show you how to make the creamiest, most delicious homemade ice cream. The key is in how quickly you freeze it. None of this hours and hours of freezing or spinning in a rock salt ice cream maker business. This recipe will go from cream to (the best!) ice cream in a matter of seconds.

Berry Cool Ice Cream - Liquid Nitrogen

 

Carol never wore her safety glasses. Now, she doesn’t need them. 

If any of you remember that gem of a poster from your old high school chemistry classroom, you’ll know exactly where I am headed here. Safety. This recipe uses either dry ice or liquid nitrogen. Both are.. well, cold. Very cold. They will hurt you if improperly used. Be careful. Wear proper gloves. Don’t let the cat taste it. Don’t let anyone swallow any of the dry ice pieces. Wait a bit before serving. You get my drift. Dry ice is available at the front of most grocery stores, and if you want to be brave and venture into the LN2 game, check with farm/welding supply companies. Better yet, befriend a handsome scientist that has some experience to give you some help!

 

Now to the fun part– the chemistry! Stay with me now. This won’t be that painful. The reason that I swear by making homemade ice cream with liquid nitrogen or dry ice is because of how quickly it freezes the cream. “Oh.. you’re just impatient?”, you may ask. Yes. That is a big part of it. Who on earth makes ice cream at home and wants to wait for hours before they can have it? Nobody that I want to know. The other reason, being a bit more molecularly gastronomical in nature, is that the extreme cold really does play a huge role in how creamy your end result will be. The extreme cold prevents the mixture from forming ice crystals, normally created during slower freezing. The fats and liquids are flash frozen, leaving less room for expansion and ice formation between molecules.

 

Blackberry Swirl Purée

 

You can mix just about anything into a solid (no pun intended…) vanilla ice cream base. I opted for this custard base, since I find it to be mucher more rich and creamy. Some summer raspberries make the base. Blackberry purée swirls make this the perfect BBQ closer. Oh… And did I mention cake pieces? That’s right. I had a bag of frozen scraps from recently making snack cakes for a friend’s baby shower. Why not? I mean… CAKE!

The end result from this magical pairing of cool chemicals and cream will give you the most smooth, almost whipped cream-like treat that you’ve ever had. It doesn’t hurt that you can impress your friends a bit and give them an opportunity to snap some flashy Instagram pictures at your 4th cookout.

Berry Cool Ice Cream

Raspberry base, blackberry swirls and snack cake pieces become the creamiest ice cream with a bit of kitchen chemistry.

Ingredients

    Prep
  • Liquid Nitrogen (~2-3 L) or Dry Ice (1-2 lbs)
  • Custard Base
  • 2 and 1/2 cups heavy cream
  • 1 and 1/2 cups whole milk
  • 3/4 cup sugar
  • 5 eggs, yolks only
  • pinch salt
  • 1/2 tablespoon vanilla bean paste
  • 1/2 to 1 cup raspberries, by taste
  • Blackberry Swirl Purée
  • 1 cup blackberries
  • 1/2 cup sugar
  • cake pieces, optional

Instructions

    Prep
  1. If using dry ice, place in paper bag and crush with hammer into very small pieces.
  2. If using liquid nitrogen, use proper dewar/protection.
  3. Review safety precautions appropriate for use of either, as they WILL hurt you if used improperly.
  4. NOTE: This recipe is for 1 quart. Multiply as needed.
  5. Ice Cream
  6. Add cream, milk, salt, half of sugar into saucepan.
  7. Heat over medium heat, slowly, to 175 F. Stir as needed with wooden spoon. Do not heat above 175, as 180 will scald the dairy.
  8. Remove from heat when it reaches temperature, mix in vanilla, let cool for 20 minutes.
  9. In mixer, cream egg yolks and slowly add remaining half of the sugar.
  10. Whip until light, about 5 minutes.
  11. When whipped, SLOWLY add 1 cup of warm custard to yolk mixture while mixing to temper.
  12. This is required to properly mix without causing the eggs to cook improperly.
  13. After tempering, slowly mix in the rest of the custard into the egg mixture on the mixer.
  14. Add raspberries (blended or crushed) and stir.
  15. While mixing, slowly pour in liquid nitrogen (carefully!). Be sure to only add a small amount at a time, as it will bubble out if too much is added.
  16. If using dry ice, slowly add pieces and watch for bubbling.
  17. Frequently stop and check the consistency and scrape the bottom of the bowl well, as it will be prone to solidifying at the bottom quickly. Not scraping could cause damage to the mixer blade.
  18. Once frozen, transfer to container, swirl in blackberry and enjoy!
