Kaju fudge is a smooth Indian cashew sweet, closely related to kaju katli, made by cooking ground cashews with sugar syrup until the mixture can be rolled and sliced. This version uses a little cardamom for fragrance and sets into tender, neat squares; careful grinding and watching the syrup are the keys to keeping it soft rather than crumbly.
Ingredients
- 2 cups (275 g) raw, unsalted cashews
- 3/4 cup (150 g) granulated sugar
- 1/3 cup (80 ml) water
- 1 teaspoon (5 g) ghee, plus a little extra for greasing
- 1/4 teaspoon (0.5 g) ground cardamom, optional
- 1 teaspoon (5 ml) rose water, optional
- 1 teaspoon (5 g) finely chopped pistachios, optional, for topping
Instructions
-
Prepare the pan and cashews. Line an 8-inch (20 cm) square pan or a small rimmed tray with parchment, leaving enough overhang to lift the fudge out later. Lightly grease the parchment with ghee. Check the cashews for any pieces of shell, then put them in a food processor or spice grinder. Pulse in short bursts until they resemble fine, dry meal. Stop and scrape the sides as needed. The grinding usually takes 1 to 2 minutes, depending on the machine.
Avoid running the processor continuously: the friction can release the cashew oil and turn the meal into a sticky paste. A few slightly larger flecks are fine, but aim for an even, flour-like texture so the finished fudge slices cleanly. If the cashews feel warm from grinding, spread the meal on a plate and let it cool before using it.
-
Make the syrup. Add the sugar and water to a heavy-bottomed saucepan, and stir over medium heat just until the sugar dissolves. Bring the syrup to a steady simmer. Let it bubble for about 3 to 5 minutes, swirling the pan occasionally rather than stirring constantly. It should look clear and slightly thickened. If using a candy thermometer, aim for about 230°F (110°C), the soft-ball stage; a thermometer is helpful but not essential for this small batch.
For a simple hand check, put a tiny drop of syrup on a cool plate, wait a few seconds, and press it carefully between your fingers. It should feel tacky and form a soft thread when your fingers separate. The syrup is hot, so do not touch it until it has cooled. If it is still watery and runs across the plate, simmer for another 30 seconds and check again.
-
Add the cashews. Turn the heat to low and add the ground cashews in two or three additions, stirring constantly with a sturdy spatula to prevent lumps. Add the cardamom, if using. Keep scraping the bottom and corners of the pan as the mixture thickens. Cook for about 5 to 8 minutes, until the mixture gathers into a soft mass and begins to pull away from the sides. The exact time depends on the pan and burner, so use the texture as your main guide.
-
Check the consistency. Spoon a pea-sized piece onto a cool plate and let it sit for 30 seconds. When cool enough to handle, it should hold together when rolled gently between your fingers and feel soft rather than wet or sticky. If it smears, return the mixture to low heat and cook for another 30 to 60 seconds, stirring, then check again. If it feels dry and cracks as you press it, it has cooked too long; take it off the heat immediately and knead in 1 teaspoon of warm water or milk to soften it.
-
Finish and shape. Remove the pan from the heat and stir in the ghee and rose water, if using. Transfer the mixture to a lightly greased plate or the prepared parchment. Let it cool for about 5 minutes, until warm but comfortable to handle. Grease your hands lightly or use a spatula to fold and press the mixture a few times until smooth. Do not knead it for a long time; excessive handling can make the cashew oil separate.
Place a second sheet of parchment on top and roll the mixture into an even layer about 1/4 inch (6 mm) thick. A small rolling pin works well, but a flat-bottomed glass also works if you press gently. Remove the top parchment and sprinkle with pistachios, pressing them lightly into the surface. Score the slab into 16 squares or diamonds with a lightly greased knife.
-
Chill and cut. Refrigerate the scored slab for 1 hour 25 minutes, or until firm enough to lift and cut without bending. Use the parchment overhang to transfer it to a cutting board. Follow the score marks with a sharp knife, wiping the blade between cuts for tidy edges. If the pieces resist, let the slab sit at room temperature for 5 minutes before cutting rather than forcing the knife through.
Tips
- Use unsalted, room-temperature nuts. Raw, unsalted cashews give the cleanest flavor and make the sugar level predictable. If you only have roasted cashews, choose unsalted ones and let them cool completely. They will give the fudge a toastier taste, and their drier texture may make the mixture thicken a little sooner.
- Pulse rather than blend. Cashews can go from fine crumbs to oily butter quickly. Short pulses give you more control. If your grinder is small, work in batches and combine the meal before adding it to the syrup. Do not add water to the ground nuts; water belongs in the sugar syrup.
- Use the texture test, not just the clock. Pan width, burner strength, and the fineness of the cashew meal all affect cooking time. A mixture that has pulled away from the sides but still feels sticky may need another short spell over low heat. Take it off as soon as the cooled sample rolls into a soft ball, because it will firm further as it cools.
- Make a simple substitute for ghee or rose water. A neutral oil can grease your hands and parchment if you want to avoid dairy, though ghee adds a subtle buttery aroma. Rose water is optional; omit it or use a few drops of vanilla extract for a different fragrance. Avoid adding extra liquid, which can make the mixture difficult to set.
Serving Suggestions
Serve the fudge in small squares or diamonds at room temperature, when the texture is tender and the cardamom aroma is easiest to notice. It is rich, so a modest piece alongside unsweetened tea or coffee makes a balanced sweet course. For a festive dessert platter, arrange it with fresh fruit and other small sweets, keeping it separate from strongly scented foods so the cashews retain their delicate flavor.
For a polished presentation, place each piece in a small paper sweet cup and add a tiny pinch of chopped pistachio just before serving. If the slab has been refrigerated, take out only the amount you plan to serve and allow it to sit for 10 to 15 minutes. The pieces soften slightly at room temperature and are easier to bite, but should not be left out for an extended gathering.
Variations
Classic diamond kaju katli style: Leave out the rose water and pistachio topping for a simple, pale cashew sweet. Roll the slab a little thinner and cut it into diamonds. Kaju katli and kaju fudge have many family and regional versions; this thicker, softly set format is one convenient home-style approach, not the only way to make the sweet.
Cardamom-free: Omit the cardamom for a more direct cashew flavor. A small amount of finely grated lemon zest can add a fresh note, though it changes the traditional flavor profile. Add zest only after taking the pan off the heat so its aroma stays bright.
Pistachio or saffron finish: Use finely chopped almonds instead of pistachios, or steep a few strands of saffron in the measured warm water before making the syrup. Saffron gives the fudge a gentle floral note and a pale golden tint. Keep the total liquid at 1/3 cup (80 ml), including any saffron-infused water.
Chocolate-dipped pieces: Once the fudge has set and been cut, dip one corner of each piece in melted semisweet chocolate and let it firm on parchment in the refrigerator. This is a modern variation rather than a traditional flavor, and the chocolate will make the pieces sweeter and richer. Keep the coating thin so it does not overpower the cashew.
Storage and Reheating
Because this fudge is moist enough to soften at room temperature, store it in an airtight container in the refrigerator. Refrigerate it within 2 hours of making, and separate layers with parchment so the pieces do not stick together. For best texture and flavor, use it within 3 to 4 days. Keep the container away from pungent foods, since the cashew sweet can pick up odors.
To freeze, place the cut pieces in a freezer-safe airtight container with parchment between layers and freeze for up to 1 month. Thaw the container overnight in the refrigerator, then bring a portion to room temperature for 10 to 15 minutes before serving. Condensation can make the surface tacky, so keep the pieces covered while they thaw. This sweet does not need reheating; avoid microwaving it, which can melt the sugar unevenly and make the texture oily or sticky.
Frequently Asked Questions
Is kaju fudge the same as kaju katli? They are closely related cashew sweets, and the names are sometimes used loosely. Kaju katli is commonly rolled thin and cut into diamonds, while “kaju fudge” often describes a thicker, softer slab cut into squares. Recipes vary in syrup method, thickness, and flavorings, but both rely on ground cashews and sugar.
Why did my fudge turn crumbly? It was probably cooked too long, so too much moisture evaporated and the cashew mixture became dry. A very coarse grind can also make the pieces break apart. For a small batch, take it off the heat as soon as the cooled sample holds together when rolled; if it is already dry, knead in warm water a teaspoon at a time while the mixture is still warm.
Can I make it without a candy thermometer? Yes. Watch for the syrup to become clear and slightly thick, then test a cooled drop on a plate for a soft, tacky thread. After adding the cashew meal, use the cooled-piece test to judge when the mixture is ready. A thermometer offers an extra reference, but the final texture of the mixture matters more than a precise cooking time.
Can I use cashew flour instead of grinding whole cashews? Yes, if it is finely ground and unsweetened. Weigh out 275 g (about 2 cups) and check that it has not clumped or become oily. Store-bought flour can vary in fineness, so add it gradually and watch the pan closely; a fine meal may thicken faster than freshly ground cashews.
Why is the mixture still sticky after chilling? It may have needed a little more cooking before shaping, or the slab may not have chilled long enough. Chill it for another 20 to 30 minutes and test again. If the pieces are still too soft, serve them as small spoonable portions rather than trying to force clean cuts; next time, cook the mixture in short increments until the cooled sample holds its shape.
Is this recipe suitable for someone with a nut allergy? No. Cashews are tree nuts, and this recipe is not appropriate for someone who must avoid them. Do not simply swap in another nut if the allergy is the reason for the substitution, and check ingredient labels and preparation surfaces for cross-contact. A nut-free confection needs a separate recipe designed around safe ingredients.
