Make the Spice Mix: In a small bowl, combine Kashmiri chilli powder, spicy chilli powder, black salt, powdered sugar, chaat masala, regular salt, and amchur powder. Mix them well and keep this homemade masala aside.
Prep the Onions: Thinly slice the onions and soak them in ice-cold water for 5 to 7 minutes. This simple trick removes their bitterness and keeps them extra crunchy for your mixed veg kachumber salad recipe. Drain the water completely before using.
Chop the Veggies: Thinly slice the cabbage, tomato, and capsicum. Grate the carrot and roughly chop the fresh coriander leaves.
Combine the Vegetables: In a large mixing bowl, add the drained crunchy onions, shredded cabbage, tomato, capsicum, grated carrot, and coriander leaves. Toss everything together.
Add the Flavours: Add 1 teaspoon of your prepared special spice mix to the vegetables. Mix it thoroughly so the veggies are nicely coated.
Add the Wet Ingredients: Squeeze a few drops of fresh lemon juice over the salad. Finally, add 2 tablespoons of freshly whisked yogurt (curd) and gently mix.
Serve Fresh: Your delicious, healthy mixed veg kachumber salad recipe is ready! Serve it immediately to enjoy its wonderful crunch.
