MARMALADE of GINGER

Ingredients

• 930 grams (approximately 1 seer) fresh ginger (whole pieces, unpeeled to start) (1 seer converts to approximately 930 g. Choose firm, young ginger for the best texture. You will peel it before use.)
• 1 sufficient quantity to fully submerge ginger lime water (calcium hydroxide solution) (Food-grade lime water (calcium hydroxide dissolved in water, also called 'slaked lime water') is used to firm the ginger. It is available at Asian or Indian grocery stores. Use enough to fully submerge the ginger pieces — roughly 1.5–2 litres. Do not confuse with citrus lime juice.)
• 58 grams (approximately 1 chhatak) pasted leaves of Indian black berry (kala jam / Java plum), fresh or dried and ground to a paste (1 chhatak converts to approximately 58 g. Kala jam is Syzygium cumini (Java plum / jamun). Use fresh leaves blended to a paste, or dried leaves ground and mixed with a little water to form a paste. These leaves are used to impart colour and a slight astringency to the ginger during boiling.)
• 1860 millilitres (approximately 2 seers) plain water (for boiling ginger with kala jam leaves) (2 seers converts to approximately 1860 ml (about 1.86 litres). Use fresh tap water.)
• 930 grams (approximately 1 seer) white granulated sugar (1 seer converts to approximately 930 g. This is used to make the candying syrup. No additional water is specified for the syrup in the original recipe — the sugar is used as-is as a boiling syrup, so add just enough water to dissolve it if needed (the original implies a dry or very concentrated syrup stage).)
• 1 pinch ground cardamom powder (Use pre-ground cardamom or grind green cardamom seeds finely. A pinch is approximately 1/16 teaspoon.)
• 1 pinch ground cinnamon powder (Use pre-ground cinnamon. A pinch is approximately 1/16 teaspoon.)
• 1 pinch edible camphor powder (Cinnamomum camphora, food grade) (Use ONLY food-grade edible camphor (also called 'Bhimseni camphor' or 'Paccha karpuram'). It is used as a flavouring in Indian confectionery. A pinch is approximately 1/16 teaspoon. Do NOT use industrial or medicinal camphor.)
• 6 drops (5–6 drops) rose essence (rose water concentrate or rose extract) (Use food-grade rose essence or concentrated rose extract, available at Indian grocery stores. Use 5 to 6 drops.)

Instructions

1. 1Weigh out approximately 930 g (1 seer) of fresh ginger. Using a spoon edge or a vegetable peeler, peel all the ginger pieces completely. Then, using a clean metal skewer, toothpick, or the tip of a sharp knife (in place of the traditional iron pin), pierce each piece of ginger all over — making small holes every centimetre or so across the entire surface. This perforation is important: it allows the lime water to penetrate deeply and later helps the sugar syrup absorb into the ginger. Place the perforated ginger pieces in a large, non-reactive bowl (glass or ceramic — do not use metal).
2. 2Prepare lime water by dissolving food-grade calcium hydroxide (slaked lime) in water according to the packet instructions — typically about 1 teaspoon per litre of water, stirred well and then left to settle so you use the clear liquid above the sediment. Pour sufficient lime water over the perforated ginger in the bowl to fully submerge all the pieces. Place a small plate or weight on top to keep the ginger under the surface. Cover the bowl with a clean cloth or lid and leave it at room temperature for exactly 3 days (72 hours). This soaking firms the ginger, mellows its raw heat, and prepares it to absorb the syrup. After 3 days, drain the lime water completely and rinse the ginger thoroughly under cold running plain water — rinse 3 or 4 times until the water runs completely clear and no chalky residue remains.
3. 3Place the rinsed ginger pieces into a medium saucepan. Add approximately 1860 ml (about 2 seers, or roughly 2 litres) of fresh plain water. Add 58 g (1 chhatak) of pasted kala jam (Indian black berry / jamun) leaves — if using fresh leaves, blend them with a tiny splash of water until a smooth paste forms; if using dried leaves, grind them to a powder and mix with a little water. Stir the paste into the water. Bring to the boil over medium-high heat, then reduce to a steady simmer. Cook until the ginger is fully softened and cooked through — it should be easily pierced with a skewer and feel tender throughout, not hard or fibrous. This may take 45 minutes to 1 hour depending on the thickness of your ginger pieces. The kala jam leaves will impart a gentle colour and subtle astringency. Once fully cooked, remove the ginger pieces from the liquid and discard the cooking water.
4. 4Once the ginger has been removed from the cooking liquid, wash the pieces 3 or 4 times in fresh plain water — place them in a bowl, cover with cold water, swirl, and pour off. Repeat. This removes any residual leaf paste and bitterness. While the ginger is being washed, prepare the sugar syrup: place 930 g (1 seer) of white granulated sugar in a separate medium-to-large, heavy-bottomed saucepan. Add just enough water to wet the sugar (a few tablespoons) so it dissolves without burning — note the original recipe does not specify extra water for the syrup, so keep this minimal. Stir over medium heat until the sugar dissolves completely, then bring to a full boil. Do not stir once it is boiling. Once the syrup is at a rolling boil, carefully drop in the washed, drained ginger pieces. Reduce heat slightly to maintain a steady boil. The ginger will begin to candy as it sits in the syrup.
5. 5Continue to cook the ginger in the boiling syrup over medium heat, stirring occasionally to prevent sticking, until the syrup becomes very thick — it should coat the back of a spoon heavily and a drop placed on a cold plate should set almost immediately into a firm, sticky mass. This stage is critical: the syrup must be very thick before you add the aromatics, as the original recipe specifies. When the syrup is very thick, remove the pan from the heat. Immediately add 1 pinch of ground cardamom powder, 1 pinch of ground cinnamon powder, and 1 pinch of food-grade edible camphor powder. Add 5 or 6 drops of rose essence. Stir everything together gently but thoroughly to distribute the spices and rose essence evenly through the thick syrup and ginger.
6. 6Remove the pan from the heat (if not already done in step 5) and allow the marmalade to cool completely at room temperature — do not rush this step. As it cools, the syrup will thicken further and the spiced, floral aromas will deepen. Once fully cold, serve one small piece of candied ginger per person as a confection or digestif. To preserve for later use, transfer the ginger pieces and syrup into clean, dry, sterilised glass bottles or jars with tight-fitting lids. To sterilise: wash jars in hot soapy water, rinse well, and place in an oven at 120°C (250°F) for 15 minutes, then allow to cool before filling. Seal the jars and store in a cool, dark place.
