Masa fat source — lard, shortening, or butter, and what each does

The fat source in tamale masa affects the flavour, the texture, and the lightness of the final tamale. After testing all three options with identical everything else: Lard: the traditional choice. Produces the lightest, most airy masa. The subtle pork flavour disappears in the steam. The high melting point means the masa stays light even when hot. Vegetable shortening: produces a slightly denser but still acceptable tamale. Slightly waxy mouthfeel compared to lard. Good choice if lard is not an option. Butter: richest flavour by far. Denser result — the tamale is more solid and heavier. Works beautifully for sweet tamales. For savoury tamales, the butter flavour competes with the filling unless the filling is mild.
