Prep: 25 min | Cook: 2 hrs 5 min | Total: 2 hrs 50 min

Cost: $5.20 total, $1.30 per serving

Ingredients

  • 150 g Cocoa beans (origin Peru) (Whole, unroasted, organic and fair‑trade beans)
  • 10 g Cocoa butter (Pure, non‑hydrogenated cocoa butter)
  • 70 g Granulated white sugar (Fine sugar for quick dissolution)

Instructions

  1. Weigh the cocoa beans

    Weigh 150 g of whole cocoa beans and place them near the roaster. Clean your work surface.

    Time: PT5M

  2. Roasting the beans

    Pour the beans into the roaster, set the temperature to 130 °C and roast for 20 minutes. Stir lightly halfway for even roasting.

    Time: PT20M

    Temperature: 130°C

  3. Cooling the roasted beans

    Spread the roasted beans on the cooling tray and let them rest for 10 minutes until they are warm to the touch.

    Time: PT10M

  4. Winnowing (shell removal)

    Transfer the cooled beans to the Tara machine. Activate the blower: the light shells are expelled, the nibs remain in the container.

    Time: PT5M

  5. Grinding the nibs (refining)

    Pour the nibs into the grinder. Run the grinding cycle until you obtain a smooth paste (cocoa mass). This process takes about 15 minutes.

    Time: PT15M

  6. Incorporating cocoa butter and sugar

    Add 10 g of cocoa butter then 70 g of sugar to the cocoa mass. Mix at medium speed until the sugar is fully dissolved.

    Time: PT5M

  7. Conching (final refining)

    Transfer the mixture to the tempering machine (conching mode). Run at 45 °C for 30 minutes to develop texture and aromas.

    Time: PT30M

    Temperature: 45°C

  8. Tempering the chocolate

    Heat the chocolate to 45 °C, then gradually lower to 31‑29 °C following the machine’s profile. Hold this temperature for 20 minutes to properly crystallize the cocoa butter.

    Time: PT20M

    Temperature: 45°C

  9. Molding and de‑bubbling

    Pour the tempered chocolate into 75 g molds each. Activate the vibrating table for 5 minutes to eliminate air bubbles.

    Time: PT5M

  10. Final cooling

    Place the molds in the refrigerator for 30 minutes so the chocolate solidifies completely.

    Time: PT30M

  11. Unmolding and tasting

    Remove the bars from the molds, gently break to check the snap. Enjoy at room temperature to appreciate the banana and red‑fruit aromas.

    Time: PT5M
