Fat in the milk cause cream like form and alcohol can prevent it...!
they are just the ice off the machine and theraresafe to eat.
Yes, ice crystals will be water, just scrape them off the ice cream will be good to eat.
They form when the ice cream freezes x
they do not form when heated! they form crystals when they are frozen bu a freezer or room tempreature.
be cause they are kept in the freezer which can from snow and ice
Ice crystals are formed when the temperature falls below the dew point. The condensation nuclei (microscopic water droplets) then freeze and become ice crystals.
The ice crystals in the ice cream form very rapidly due to the intense cooling effect of the liquid nitrogen. They do not have time to grow large. The "grit" you taste in cheap ice cream is made of large ice crystals. small crystals = no grit
The faster ice cream freezes, the smaller the crystals of water in it as they don't have much time to form - eg. if you are like Heston and use liquid nitrogen to make icecream it freezes really quickly and is lovely and smooth. This is also why icecream makers constantly stir the ice cream when it is freezing to keep the crystals small and the icecream stays smoother. Ice cream that has re-frozen has solidifed much more slowly so larger ice crystals can form - this not only affects the texture but also the taste of the icecream.
prebake your pie shell
yes you can, it freezes faster so be careful of crystals form.
water vapor or humidity The food contains ice when it is n the freezer. This ice can evaporate ( a process called sublimation this increases the content of water vapor in the package. If by some chance an ice crystal starts to grow on the surface of the food or on the package this vapor will freeze on this in preference to the ice within the food. This loss of ice in the food and growth of external ice crystals is called freezer burn. If the temperature of the food cycles as it does in most freezers this process is accelerated. And so you ice cream gets dried out and there are lots of beautiful ice crystals on the lid and on top of the ice cream. To prevent the problem make sure the package has little or no space above the food.
That depends on how cold the ice cream is in the first place. Remember that completely thawing ice cream and then refreezing it will cause large ice crystals to form in the mixture and will ruin your ice cream. This is the same thing that happens to a bucket of ice cream when it gets old, ice crystals form on the top of the ice cream and bottom of the lid.
Yes. Salts can form crystals (salt crystals).
No. A bag that has been vacuum sealed prevents moisture and air from getting to the food.
The ice crystals generally mean that the frozen food has dried out some and could be related to freezer burn. As long as it hasn't become rancid or developed freezer-burn flavor, the food could still be edible.
