As you can already tell, Goat cheese is made from goat’s milk. Other types of cheese are made from cow’s milk, sheep’s milk, goat’s milk, water buffalo’s milk or a combination of 1 or 2 of those.
Needless to say, Goat cheese has a unique flavor and texture because of its main ingredient (goat’s milk). As such, the cheese also carries a unique texture because of its goat’s milk content.
When recipes call for Goat cheese, it would be good to use the exact same ingredient so as not to alter the taste of a dish. However, if you don’t have Goat cheese (it’s one of those hard-to-find cheeses, you know), you still have the option of continuing with the recipe. After all, you can use other types of cheese to substitute for Goat cheese.
