Notes
Recipe Notes
Nuts: Traditionally almonds and pistachios are included. Swap cashews with pistachios. For pistachios do not use the salted ones.
Rose flavors: If using gulkand (rose petals preserve), then reduce the sugar to ⅓ cup. Or add 2 tablespoons rose water.
Thandai paste consistency: Grind the paste very finely, especially if preparing for kids. You can even strain the thandai paste if you want.
Peeling almonds: You can use peeled almonds if you want. Just blanch the almonds separately and then peel them.
Vegan option: Use almond milk, cashew milk or lite coconut milk. Almond milk is a better choice for this recipe.
Seeds: Skip poppy seeds and melon seeds if they are not available in your country. You can replace melon seeds with unsalted peeled pumpkin seeds.
Flavorful Variations
