Leipäjuusto Leipäjuusto Leipäjuusto (bread cheese) or juustoleipä, which is also known in the United States as Finnish squeaky cheese, is a fresh cheese traditionally made from cow's beestings, rich milk from a cow that has recently calved. Reindeer or even goat milk can also be used. Commercially available versions are typically made from cow's milk, and they lack some of the colour and flavour because of this. The cheese originally comes from Southern Ostrobothnia, Northern Finland, and Kainuu. The milk is curdled and set to form a round disk from two to three centimeters thick. After this, leipäjuusto is baked, grilled,
Modular form The situation with modular forms is precisely analogous. Modular forms can also be profitably approached from this geometric direction, as sections of line bundles on the moduli space of elliptic curves. If "f" is holomorphic at the cusp (has no pole at "q" = 0), it is called an entire modular form. If "f" is meromorphic but not holomorphic at the cusp, it is called a non-entire modular form. For example, the j-invariant is a non-entire modular form of weight 0, and has a simple pole at i∞. Other common generalizations allow the weight "k" to not be an integer,
