The reason your ice cream turns grainy is probably a combination of factors. Low-fat milk is more likely to cause the problem than full-fat milk. Using cheap vegetable oils can also cause the ice cream to taste gritty. Here are some steps to take to fix this problem. A better-sealed container is another solution. It will help you enjoy the ice cream sooner.
In some cases, your ice cream isn’t properly whipped, so the consistency of the ice cream is distorted. This causes chunks of ice crystals throughout the ice cream. While this may not taste very pleasant, it is still safe to eat. In other cases, the ice cream might be poorly-formulated or undergo a heat shock that causes the ice cream to turn grainy in taste. In either case, the problem is likely caused by crystallized lactose, which isn’t soluble and will form crunchy bits.
Unbalanced ice cream recipes may be the culprit. Too much “free” water will form larger crystals. Because ice cream contains liquid ingredients, reducing the amount of “free” water in the recipe can make the ice cream more stable and less icy. However, too little water will make the ice cream brittle and bland, while too much can give it a sandy-like texture.
One way to fix this problem is to use a thermometer to check the temperature of the ice cream. It is important to remember that when the ice cream is fresh out of the freezer, it is only partially frozen. A further freezing process may be needed to make the ice cream firm and smooth. If this happens, you’ll have to scoop it several times before it freezes. However, this will increase the freezing time and affect the smoothness of the ice cream.
