Pineapple Bun
“Soft sweet bun under a cracked sugar-cookie crust — no pineapple inside; the name is for the crust pattern.”
The bite
Pulled apart while still warm, the bun is feathery and faintly sweet; the top crust shatters under your thumb into buttery crumbs that taste like a sugar cookie. Best in the first 20 minutes after baking — the contrast between crisp top and pillowy interior is the whole point. Cha chaan teng order: split a hot one, slap in a 1cm slab of cold butter — that's bo lo yau (菠萝油).
Where it comes from
Hong Kong cha chaan teng invention from the 1950s, when the city's bakeries adapted the European «mexican bun» (a sweet bread topped with cookie crust) using lard or butter, milk powder, and the higher sugar level Cantonese palates wanted. The grid score that turns into the «pineapple» pattern after baking was the styling addition that gave the bun its name. Bo lo yau (with cold butter) followed in the 1960s as iceboxes spread.
What makes it work
The crust is a separate dough — high sugar, low water — sat on top of the bread dough so it can't rehydrate. During baking the bread underneath rises and stretches the rigid sugar layer, which cracks along the score lines into the pineapple pattern. Use baking powder instead of soda and the crust puffs instead of crackling. Use cake flour, not bread — gluten in the crust would make it leathery instead of friable.

Punch down the bun dough. Divide into 8 pieces (~60g each), shape into smooth balls, rest 15 minutes on a lined tray.

Divide crust into 8 pieces (~30g each). Press each between plastic into a 7cm disc. Drape over each bun, pressing gently so it covers the top half.

Score a diamond grid into each crust with a knife — shallow, 2mm. Brush with beaten egg yolk for shine. Proof 30 minutes at room temperature.

Bake at 190°C for 14 minutes until tops are deep gold and the crust has cracked open along the score lines. Eat warm; the crust softens within an hour.
