Nama chocolate (Japanese raw chocolate)

Japan's iconic raw chocolate: a silky ganache slab of fresh cream and premium dark chocolate, cut into precise squares and dusted with cocoa powder

Origin: Japan

From the journey of Cocoa.

Nama (生) means 'raw' or 'fresh' in Japanese, and nama chocolate (nama choko) refers to the brief shelf life and fresh cream content that distinguishes it from ordinary chocolate. The product was pioneered by Royce' Confect, founded in 1983 in Sapporo, Hokkaido (Japan's dairy heartland) who began producing ganache slabs of extraordinary smoothness made with Hokkaido fresh cream and imported Belgian chocolate in the early 1990s. The product became a sensation across Japan, and Royce' Nama Chocolate is now one of the most iconic gift items in the country. But the broader Japanese chocolate story is equally fascinating: introduced to Japan via Dutch traders at Nagasaki in the Edo period (17th century), chocolate was initially a curiosity for the elite. It was the Meiji-era Westernisation (1868 onwards) and post-WWII American influence that made chocolate ubiquitous. Japan then did what it does with most adopted foods: refined it obsessively, creating a chocolate culture of extraordinary quality and creativity: from Kit Kat's 300+ regional flavours (matcha, wasabi, sake) to Pocky, to the craft chocolate movement now centred in Tokyo. Nama chocolate is the purest expression of this perfection: just chocolate and cream, cut with mathematical precision.

Ingredients

base

  • 300 g high-quality dark chocolate (58–65% cocoa solids), very finely chopped
  • 150 ml fresh double cream (heavy cream): ideally with a high fat content
  • 20 g unsalted butter, at room temperature
  • 1 tbsp whisky, rum, or Grand Marnier (optional)

finishing

  • 3 tbsp Dutch-process cocoa powder, generously sifted: for dusting

Method

  1. Line a 15×15 cm (6×6 inch) square baking tin or container with cling film, leaving a generous overhang on all sides.
  2. Place the finely chopped chocolate in a heatproof bowl. Heat the cream in a small saucepan over medium heat until it just comes to a simmer. Pour the hot cream over the chocolate.
  3. Leave undisturbed for 90 seconds, then stir gently from the centre outwards with a spatula until the ganache is completely smooth and glossy. If any chocolate remains unmelted, set the bowl briefly over a bain-marie.
  4. Add the butter and stir until fully melted and incorporated. Add the whisky if using.
  5. Pour the ganache into the prepared tin and smooth the top with an offset spatula or the back of a spoon. Tap the tin gently on the counter to release air bubbles.
  6. Refrigerate for a minimum of 2 hours (or overnight) until the ganache is completely set and firm enough to cut cleanly.
  7. Sift a generous layer of cocoa powder over a clean work surface. Lift the ganache slab out using the cling film overhang and place on the cocoa-dusted surface. Sift more cocoa powder over the top.
  8. Cut into 5×5 rows of 25 squares using a sharp knife dipped in hot water and wiped dry between each cut. This is essential for clean, sharp edges.
  9. Transfer to a serving plate or box lined with paper. Serve cold, directly from the fridge.

Notes

Due to the fresh cream content, nama chocolate must be refrigerated and consumed within 5–7 days. It cannot be left at room temperature for more than 2 hours. For the best flavour, use single-origin Belgian, Swiss, or Japanese-sourced dark chocolate at 58–65%: higher percentages can make the ganache too firm and less melt-in-the-mouth. Flavour variations: infuse the cream with matcha powder (1 tbsp), yuzu zest, or hojicha (roasted green tea) before pouring over the chocolate.
