Tamales — the ancient preparation of masa (nixtamalised corn dough) spread onto a corn husk or banana leaf, filled, wrapped, and steamed — require the masa to achieve a specific texture: light, slightly spongy, with enough fat to create the characteristic tender-yet-structural quality that allows the steamed tamale to hold its shape while yielding at the first bite. The beating of fat into masa is the central technique — without sufficient beating, the masa is dense and heavy.
**Masa preparation:** - Masa harina (nixtamalised corn flour) hydrated with warm stock or water — never with cold liquid, which produces a stiff, difficult masa. - The beating: masa beaten with lard (traditionally) or vegetable shortening until the fat is fully incorporated and the masa becomes noticeably lighter. The float test: a small ball of masa dropped in cold water should float when sufficient air is incorporated. - Lard specifically: the saturated fat of lard produces a different final texture than vegetable shortening — lighter, more tender, with a specific flavour. [VERIFY] Arronte's fat specification. **The corn husk:** - Dried corn husks soaked in hot water until pliable (30–45 minutes) before use. - The masa spread on the inside (rough) surface of the husk — the masa grips the rough surface. - The filling placed in the centre of the masa. - Folding: both long sides of the husk brought to the centre (enclosing the masa), then the empty lower end folded up. **The steam:** - Vertical in a steamer — the tamales must stand upright, open end up. - Steam for 45–60 minutes. The doneness test: the masa should pull away cleanly from the husk when the husk is folded back. If it sticks, more steaming is required. Decisive moment: The float test with masa before assembly — the same test as medu vada (IC-45). A ball of masa that floats has sufficient air incorporated. A ball that sinks produces dense, heavy tamales regardless of any subsequent technique.
