Pineapple Cake

Pineapple cake is rooted in Taiwan's pineapple industry. From 1906 the Governor-General's office brought in the more commercial Hawaiian Kai-ying (Cayenne) variety, and a cannery set up by Okamura Shotaro at Jiuqutang near Fengshan turned the island into a major canned-pineapple exporter — by 1920 the town of Yuanlin alone held some twenty-eight canning plants. With cheap pineapple and a tradition of fruit-filled wedding pastries (a pineapple-filled cake, 凤饼, was one of the auspicious betrothal cakes; pineapple in the Hokkien dialect sounds like 旺来, 'prosperity coming'), bakers shrank the old large 凤饼 into the small individually wrapped cake known today. The cheaper commercial filling long mixed shredded winter melon with pineapple — milder, sweeter, and less sticky — which is the older mainstream style. The pure-pineapple 土凤梨酥, tart and fibrous, was popularized by the brand SunnyHills (微热山丘): founded in Nantou in 2008 with its products launched in 2009, it built its line on the century-old Kai-ying pineapple grown on the Bagua Mountain foothills, dropping the winter melon entirely and reframing the cake around real fruit.

Snap the cake and the crust shatters into fine, buttery, melt-in-the-mouth crumbs, smelling of toasted milk powder. Inside, a dense amber paste of cooked pineapple — chewy, almost candied, glossy and slightly translucent. A good 土凤梨酥 reads tart-sweet with a faint fibrous bite from the fruit; the winter-melon style is rounder and sweeter, smoother on the tongue. The pleasure is the contrast: dry crisp shell against a sticky, fragrant, fruit-acid center.

Two things drive the texture. The crust starts from creamed butter: beating soft butter with powdered sugar whips in countless tiny air bubbles, and during baking that aerated fat — plus the way butter coats the flour and limits gluten — gives the short, crumbly 'melt' rather than a chewy crumb; the milk powder adds proteins and lactose that brown and deepen the aroma. The filling is the long reduction: fresh pineapple (with or without winter melon) is cooked down over low heat to drive off water, and as the sugars concentrate, Maillard browning and caramelization turn it amber and intensely fragrant, often finished with maltose, whose resistance to crystallizing keeps the paste pliable and glossy. The mix must be cooked nearly dry — a wet filling won't hold its shape and splits the crust in the oven. Baked around 170-180°C, the cakes are turned partway so both faces set to an even gold.
