Kurikinton — Sweet Chestnut Gold and New Year Symbolism

Ingredients

• For the gardenia water
• 2 kuchinashi no mi (dried gardenia fruit), soaked in boiling water until deep yellow, then strained
• 100 ml boiling water, for soaking the gardenia fruit
• For the sweet potato base
• 600 g satsuma-imo (Japanese sweet potato), peeled and cut into rounds
• 150 g sugar
• For the kuri no kanroni
• 200 g dried chestnuts, soaked 24 hours in cold water
• 500 g sugar
• 300 ml water

Method

1. 1
   Soak the dried kuchinashi no mi in 100 ml of boiling water. Leave until the liquid is a deep, vivid yellow. Strain and reserve the coloured water; discard the fruit. The liquid should be strongly pigmented — pale yellow is insufficient.
2. 2
   Drain the chestnuts after their 24-hour soak. Place in a saucepan, cover generously with fresh cold water, and bring to a simmer. Cook for 1 to 1½ hours until fully tender throughout. Drain.
3. 3
   Combine the 500 g sugar and 300 ml water in a wide saucepan and bring to a simmer, stirring until the sugar dissolves. Add the cooked chestnuts. Simmer gently, without agitation, until the chestnuts are translucent throughout and the syrup coats them in a glossy glaze — this is kuri no kanroni. Remove from heat and hold the chestnuts in their syrup.
4. 4
   Place the satsuma-imo rounds in a saucepan. Add enough of the strained gardenia water to cover; supplement with plain water if needed. Bring to a simmer and cook until the sweet potato is completely tender — a skewer should meet no resistance anywhere in the piece.
5. 5
   Drain the cooked satsuma-imo, reserving a small quantity of the now golden cooking liquid. Press the sweet potato through a fine-mesh strainer into a clean saucepan, working in batches. No fibrous matter should pass through; the result is a smooth, uniform mass. This is where the dish lives or dies: any fibre left in the paste cannot be corrected, and under-pressing produces an inconsistent final texture that is irrecoverable.
6. 6
   Set the saucepan of strained satsuma-imo over low heat. Add the 150 g sugar and stir continuously. Add spoonfuls of the reserved golden cooking liquid or of the kuri no kanroni syrup to loosen as needed. Cook, stirring, until the sugar is fully dissolved and the paste is thick, cohesive, and holds its shape when a spoon is drawn through it — it must be moldable but not dry.
7. 7
   Taste the sweet potato base. Kurikinton must be noticeably sweet — generously so, functioning as both confection and auspicious food. Adjust sugar if necessary at this stage.
8. 8
   Fold the glazed chestnuts gently into the golden paste, preserving their shape. The finished kurikinton should show whole or large pieces of chestnut suspended in the deep-gold sweet potato base. Transfer to a lacquerware or ceramic osechi box. The colour should read as gold.
