🛟 Measurement Rescue

A swap changes more than flavor — it changes volume. Substituting an egg or switching leaveners can shift how much batter you actually have, and a 9x13 bake scales differently than an 8x8. Before you commit to a new pan size or a doubled batch, run the numbers through the Kitchen Conversions scaling section so the swap doesn't trade one problem for another.
