English: What is the difference between the griddle (machavas) and the deep pan (marcheshes)? The marcheshes is deep, and its products “creep” (soft and moving because of the depth of oil); the machavas is flat, and its products are hard. The marcheshes has a cover; the machavas has none.
In Sifra / Menachos: The two vessels produce recognizably different textures. The deep pan retains oil so the mixture remains soft; the flat griddle yields a firmer product. The names follow the vessels, not merely the cooking method.

What Is Learned
Machavas and marcheshes are distinct sacred vessels; each produces a different consistency of mincha and therefore constitutes a separate type.
