Beyond the Recipe

Sun Cake (Tai Yang Bing / 太阳饼)

What the recipe doesn't tell you

Taichung, Taiwan — 20th century local specialty · Chinese — Taiwanese — Pastry

Taichung's signature gift pastry: a flaky, multi-layered Chinese shortcrust pastry filled with a sweet malt sugar paste (mai ya tang). The pastry uses the same Chinese flaky technique (water dough wrapped around fat dough) as wife cake, but the filling is distinctively honey-sweet malt sugar. A Taiwanese gift culture staple — boxes of sun cakes are taken back from Taichung visits.

Intensely sweet malt sugar against subtly salty, multi-layered flaky pastry; the contrast of sweet filling and short-flaky pastry is the entire appeal

Where It Goes Wrong

Under-laminating the pastry — too few folds result in thick layers rather than paper-thin flakiness Malt sugar paste too hot — becomes too firm and hard when cooled Not scoring before baking — the signature pattern is non-optional for sun cakes

Chinese flaky pastry: two doughs — water dough (flour, water, lard) and oil dough (flour, lard only); wrap oil dough in water dough, roll and fold multiple times Malt sugar filling (mai ya tang): malt syrup with butter and a little salt — must be cooked to correct temperature or it becomes too hard Individual small discs, slightly flattened — about 6–7cm diameter Score a sunburst pattern on top before baking for the 'sun' appearance
