Japan (Kyoto Toraya as the oldest premium producer, since 16th century; Edo period neri yokan development; nationwide confectionery tradition)
Yokan (羊羹, literally 'sheep soup' from the Chinese name — though the Japanese version has no sheep) is one of Japan's most important and long-established wagashi confections — a firm, sliceable jelly made from red bean paste (anko), sugar, and either agar-agar (kanten) or wheat flour gelatin, sold in rectangular blocks and consumed in thin slices. The confection has been made in Japan since at least the 16th century and was refined into its modern agar-based form (neri yokan) in the Edo period. Quality yokan is distinguished by the smoothness of its anko base (requiring premium koshian strained paste), the precise agar calibration (too firm is chalky, too soft is unstable), and the balance of sweetness. The major varieties include: neri yokan (firm, made with kanten agar and anko — the standard block form); mizu yokan (水羊羹, 'water yokan' — a softer, more hydrated version served cold in summer); and fruit yokan (incorporating seasonal fruits — yuzu, chestnut, strawberry). Premium craft yokan producers (Toraya, Suzuki Shingo) age their anko and calibrate their agar with extraordinary precision, producing yokan that commands high prices as gifts. A 160g block of premium yokan can cost 2,000–5,000 yen.
Smooth, cleanly sweet anko; the agar's neutral, slightly firm texture contrasting with the smooth paste; bitter matcha is the classic pairing partner
{"Koshian quality: smooth, strained anko paste is essential; grain or skin fragments compromise the smooth texture","Kanten calibration: agar-agar quantity determines firmness; 0.5–0.8% agar content for neri yokan; less for mizu yokan","Mizu yokan summer version: higher water content, softer texture, served chilled — seasonal format","Block and slice service: thick blocks cut into 5–8mm slices at service; paired with unsweetened green tea","Premium gift packaging: yokan at top wagashi shops is a premier gift product with gift-appropriate packaging"}
{"Wet the mould before pouring for easy release — wet silicon or plastic moulds work best","Yuzu yokan: add yuzu zest and a small amount of yuzu juice to the mix before setting","Paired with matcha or gyokuro: the bitterness of the tea is the ideal counterpoint to yokan's sweetness","Mizu yokan served in a bamboo container (take no utsuwa) is a classic summer kaiseki dessert presentation"}
{"Over-boiling the agar — drives off the setting power; simmer at low heat until dissolved","Lumpy anko mixture — must be smooth before combining with agar; strain if needed","Setting at room temperature in summer — in warm weather yokan may not set properly; refrigerate","Cutting warm yokan — it must be completely cold before slicing; warm yokan tears and loses its clean surface"}
