This brief makes the case that sucrose crystallization is an ideal entry point for teaching crystal systems, nucleation theory, and crystal habit to youth members and first-year collectors. The argument: the process is observable in real time (unlike quartz growth), repeatable in a kitchen, edible after the lesson, and produces specimens that genuinely exhibit the properties we ask beginners to memorize. Sections cover: the crystallography of sucrose; a comparison of rock candy crystal habit to common ARE minerals; a lesson plan for chapter meetings; and a brief field section on "advanced sucrose mineralogy" (rock candy identification under a hand lens, complete with a formal ARE specimen card template). Includes an appendix on Pop Rocks as a vesicular analog for volcanic degassing, with notes on the known safety record of carbonated confectionery in educational settings.
