Kaju Katli: The Authentic Indian Cashew Fudge You Can Make at Home

The single-thread test is your definitive guide. Dip a clean, dry spoon into the syrup, wait 3 seconds for it to cool, then press a drop between your thumb and forefinger and pull apart slowly. A clean, unbroken thread of 1–2 cm indicates single-thread consistency — the correct stage for kaju katli.

On a sugar thermometer, single-thread corresponds to 110–112°C. If you over-cook to two-thread (114–116°C), the katli will crystallise and turn grainy. Under-cooked syrup produces katli that stays sticky even after cooling. The window between underdone and overdone is approximately 30–45 seconds on medium heat — watch closely from the 4-minute mark.

Graininess in kaju katli has two common causes. First, the sugar syrup was cooked too far past single-thread consistency — the excess heat causes sugar crystals to form as the mixture cools. Second, you stirred the syrup after it reached a boil, which seeds crystallisation. Stir gently only until the sugar fully dissolves, then leave the syrup completely undisturbed.

Adding 5 drops of lime juice to the boiling syrup prevents crystallisation. Also ensure your cashew powder is completely dry. For dry fruits benefits beyond taste, quality raw cashews like Sindhi's premium whole cashews have a naturally lower water content, which translates to finer grinding and smoother katli.

Homemade kaju katli stays fresh for 5–7 days at room temperature in an airtight container, or up to 2 weeks refrigerated. Unlike dairy-based sweets, there is no milk or cream in traditional kaju katli, so it resists spoilage well.

For longer storage, layer individual pieces between parchment sheets inside the container to prevent sticking and moisture transfer. If the katli develops a white coating (bloom), it is sugar crystallisation, not mould — it is still safe to eat. This is why one of the key dry fruits benefits is their natural keeping quality: sugar-preserved confections made from low-moisture nuts like cashews stay fresh far longer than flour-based sweets.

Technically yes, but not recommended. Roasted cashews have already been exposed to heat, which affects the way oil distributes during grinding — you will reach oily, paste-like texture faster than with raw cashews, leaving a narrower safe processing window. The flavour also changes: roasted cashew katli has a more toasted, less delicate taste than the classic version.

For traditional kaju katli, use raw, premium whole cashews. Sindhi Dry Fruits whole cashew nuts are sun-dried at low temperatures to preserve the natural flavour compounds that give authentic katli its distinctive clean sweetness. If you want a toasted note, grind 90% raw and 10% very lightly roasted cashews together.

The most classic addition is pistachio — finely sliced and pressed into the surface before cutting, it adds visual contrast and a mild nuttiness. A saffron (kesar) variation replaces cardamom with a few soaked saffron strands dissolved in one tablespoon of warm water, stirred into the dough at the end.

For a premium dry fruits benefits twist, add two tablespoons of almond powder alongside the cashew powder — almonds provide Vitamin E and a slightly denser texture. A rose petal version (gulab kaju katli) uses a teaspoon of food-grade rose water in place of plain water. For a festival gift-worthy presentation, press a single whole pistachio kernel into the centre of each diamond before the katli fully sets.
