The first rule when it comes to the ingredients you will use to manufacture your frozen desserts is to always use the highest quality possible. With some ingredients, such as dairy, it is more important to keep an eye on quality than with others, like granulated sugar, the quality of which is about the same everywhere. There are many different purveyors of dairy products. Some of the larger dairies will opt for mass-production techniques, which increase volume and sales but may result in products lacking in quality, flavor, richness, or mouth feel. Smaller farms generally produce superior dairy products because it is in their best interest to do so. Why? Because they can’t necessarily compete with price, but they can compete with quality. However, you can expect consistency from mass-production farms, whereas the medium to small farm may not be able to guarantee consistency in something such as the fat content of their heavy cream. If the fat content is not always the same, your ice cream won’t always come out the same. This is why it is important to establish a good relationship with your dairy provider(s) so you can receive a consistent product from them. Just because a product is certified organic and the farmer’s family has produced dairy product for many generations doesn’t necessarily mean that it will always be good.
