La señal inequívoca de que tu tarrina de helado se derritió y se volvió a congelar (y por qué es importante)
Los fabricantes de helados deben tener en cuenta muchos elementos al elaborar sus recetas. Hay cuestiones sobre los tipos de lácteos, las proporciones de líquido y azúcar, los niveles de grasa butírica y, por supuesto, los importantísimos saborizantes.
Ice cream makers must consider many factors when developing their recipes. There are questions about the types of dairy products, the proportions of liquid and sugar, the levels of butterfat, and, of course, the all-important flavorings. But there's one thing that's beyond dispute: a fundamental ingredient, perhaps the most important for enjoying ice cream, and one that's completely free: air.
Air is the essential component that gives ice cream its smooth, light, and fluffy texture. Although it costs nothing, manufacturers must make an effort to incorporate it into their processes. Even if you've never seen air listed as an ingredient in ice cream, you'll certainly notice its absence if it's missing or if some of it has been lost. Unfortunately, it usually disappears when ice cream melts and refreezes.
Perhaps more than many other products, ice cream is difficult to transport efficiently. The supply chain, from the factory to the supermarket freezers, is riddled with points where the frozen dessert moves and experiences temperature changes. Ice cream is technically a frozen foam, so as it melts, it deflates and becomes dense and hard. If you've ever opened a tub of ice cream and found that it feels more like a solid, milky ice cube than a fluffy cloud, and that it doesn't fill the entire container, it's likely lost air. This is a problem for several reasons.
Problems with airless ice cream
To begin with, the fact that ice cream melts and refreezes affects how easy and enjoyable it is to eat. Several factors influence how easily it can be served, one of which is air. Trying to serve ice cream without it is fussy; it won't be smooth and creamy enough for a spoon, or even a special utensil, to cut through easily. When you finally manage to transfer it to a bowl, it may taste cloying or heavy. Ice cream is made with this lightness in mind (to varying degrees, as evidenced by the difference between gelato and ice cream). When air isn't present to soften the flavor distribution on the palate, you get a direct hit of sugar and fat. Melted and refrozen ice cream can also have a grainy texture or emit an unpleasant odor, so keep your senses alert for these issues.
While it's possible to revive frozen ice cream at home with a blender, it's not recommended. This deflated treat can pose a health risk due to temperature fluctuations. If the ice cream has picked up harmful bacteria during shipping, these can survive even in the freezer. So, whether you're trying out Ben & Jerry's' many flavors or making thick, creamy milkshakes, make sure the ice cream is fresh. Not even the most delicious flavor is worth the risk.
