Peel and core 2 medium-sized apples, then slice them into 1 cm thick rings. Keep the apple rings aside.
In a bowl, mix 100 grams of maida (all-purpose flour), 50 grams of cornflour, a pinch of baking soda, and 1/4 teaspoon of cardamom powder. Gradually add water to make a smooth, thick batter. Ensure there are no lumps.
In a pan, prepare sugar syrup by boiling 250 grams of sugar with 250 ml of water. Add a pinch of saffron strands and 1/4 teaspoon of lemon juice. Cook until the syrup reaches a one-string consistency. Keep the syrup warm.
Heat oil in a deep frying pan for deep frying. Dip the apple rings in the prepared batter, ensuring they are evenly coated.
Carefully slide the coated apple rings into the hot oil and deep-fry until they turn golden brown. Flip occasionally for even cooking.
Remove the fried apple rings from the oil and drain the excess oil on a paper towel.
Soak the fried apple rings in the warm sugar syrup for 2-3 minutes, ensuring they are well coated.
Remove the apple jalebis from the syrup and place them on a serving plate. Garnish with chopped pistachios or almonds.
