Traditionally Bengalis are a non-vegetarian community. We do eat a variety of vegetables but those of us from West Bengal swear by one particular vegetarian dish and that is aaloo posto, aaloo is potatoes and posto is the Bengali word for poppy seed. A Bengali is usually lost without fish but if you tell him or her that there is aaloo posto then you are sure to see the relief on his/her face.
It is a simple dish and very easy to cook. Different households have different recipes, therefore after seeing my recipe if you compare notes with other Bengalis you may find some difference.
