Introduction:
Sahjan flowers, also known as drumstick flowers, are a popular ingredient in many Indian dishes. They have a unique flavor and are often used in curries, soups, and stir-fries. While they are used in various states across India, Sahjan flowers are particularly popular in the state of Maharashtra.

Explanation:

1. Maharashtra:
Sahjan flowers are widely used in the state of Maharashtra, which is located in the western part of India. Maharashtra is known for its rich culinary traditions and diverse cuisine. Sahjan flowers are commonly used in Maharashtrian dishes like sabzis (vegetable curries), dal (lentil soup), and bhajis (fritters). They add a unique flavor and texture to these dishes.

2. Uttar Pradesh, Kerala, and Punjab:
While Sahjan flowers are used in various other states as well, they are not as commonly used as in Maharashtra. In Uttar Pradesh, Kerala, and Punjab, other ingredients and spices take precedence in the local cuisine. However, it is worth noting that Sahjan flowers can still be found in some traditional dishes in these states.

3. Usage in other states:
In Uttar Pradesh, drumstick flowers are sometimes used in regional dishes like korma (a creamy curry) or as a garnish for biryani (a fragrant rice dish). In Kerala, they are occasionally used in curries and soups, but other ingredients like coconut, fish, and spices are more prominent. In Punjab, Sahjan flowers are not widely used in the local cuisine, but they may be found in some specialty dishes.

Conclusion:
In conclusion, Sahjan flowers are cooked and used in various parts of India, but they are particularly popular in the state of Maharashtra. They add a unique flavor and texture to Maharashtrian dishes and are an essential ingredient in many traditional recipes. While they may be found in dishes from other states like Uttar Pradesh, Kerala, and Punjab, they are not as commonly used as in Maharashtra.
