Black Soybean Tea (黒豆茶, Kuromame-cha)

Black soybeans look almost too hard to become tea, little black beads with no mercy in them. Give them a dry pan and patience, and they turn generous. Kuromame-cha is only whole beans roasted until their skins split, then steeped in hot water until the cup goes clear amber. No tea leaf, no caffeine, no sugar needed.

The roast is the detail that decides it. Too pale, and the tea tastes raw and beany. Too hard, and bitterness arrives before sweetness, a stern guest who won't leave. We roast slowly so the skin opens and the center warms through; those little cracks are not damage, they're the doors the water needs.

This is winter comfort, especially near New Year, when kuromame sit in osechi ryōri as a wish for steady health and work done well. The tea is plainer than the lacquered New Year bean, and that is its charm. Honmono doesn't always wear ceremony. Drink it as it is, then eat the softened beans at the bottom. Nothing hidden. The bean gives the cup, then stays for the meal.
