Cheese

Also searched as: Gruyère, Emmental, parmesan, raclette, mozzarella

In short: Cheese is curdled milk protein with fat. Whether it melts creamily or turns stringy and greasy depends on age, moisture and acidity.

Picture it

Like a net of protein with fat and water trapped inside.

What happens

When melting, the protein network loosens. Young, moist cheeses melt creamily. Very old, dry cheeses tend to release fat. Too much heat makes the protein contract: rubbery, with pools of fat.

Rules of thumb

  1. Grate finely and melt over medium heat.
  2. For fondue, white wine and a little starch: acid and starch hold the together.
  3. Stir parmesan into pasta only over medium heat.
