Bhapa is steamed vegetables or fish with spices, and shak means any leafy green (including mustard greens) slightly wilted in oil and served with nigella seeds. Some fruits you’re likely to encounter are mango, watermelon, and quince. You can find organic Bengali and Indian food in the capital of Dhaka.
