Kochur Loti  (also called kochu lati or taro stolon/colocasia stem) is a classic Bengali seasonal delicacy – the soft, fibrous stems of the taro plant cooked into a flavorful sabzi. In Bengal, it’s often paired with prawns (chingri) in a light mustard-coconut gravy, or made niramish (vegetarian) with poppy seeds or coconut. It’s earthy, slightly tangy, and pairs perfectly with hot rice for a comforting meal.

As a Jaipur home cook who loves regional Bengali dishes (tested this 3-4 times with photos for that perfect itch-free, flavorful result), this version captures the authentic taste – no throat itch if prepped right, creamy mustard notes, and subtle sweetness from coconut. It’s nutritious (high fiber, low cal), seasonal, and great for monsoon vibes!

Serves 4 | ~250-350 kcal per serving (with rice).
