Slice the Crisco into small pieces then add to a pot over low heat. (Non-stick is not recommended.) Stir slowly and constantly until liquid. Never let the mixture get hotter than is comfortable for your hand.

Once the Crisco is melted into a liquid, gradually add in sugar while continuing to stir. Continue until all the sugar is mostly dissolved. (The remainder will dissolve when the snow/water is added later.)

Once the mixture is all liquid, transfer it to a large bowl and continue to stir. Add in ¼ cup of water (or 1 cup of snow) to the mixture. As the mixture starts to cool it will thicken and get more fluffy and white. Then, add in the other 1/4 cup of water (or 1 cup of snow). If needed, use a hand mixer on medium-high for about 60 seconds to increase the fluffiness of the mixture.

When the mixture is as fluffy and white as you can get it, fold in the berries.

Form into desired shape or place in desired container and then put in freezer to firm for 1 hour before serving.
