Premium Sweet Guava Chutney” (often referred to as Amrud ki Khatti Meethi Chutney or Jamfal Chutney) is a gourmet, sweet-and-spicy Indian condiment made from ripe or semi-ripe guavas, cooked down with sugar or jaggery and traditional spices. A 200g – 300g jar is a common size for this product. 
Here is a breakdown of what characterizes this product:

Key Characteristics
Flavor Profile: A balanced blend of fruity sweetness from the guava, mild heat from red or green chilies, and tangy notes, often with hints of ginger, cumin, and black salt.
Texture: Thick, jammy, and sometimes slightly chunky due to the fruit, or smooth depending on the preparation.
Ingredients: Typically includes diced guava, jaggery/sugar, mustard oil, mustard seeds, cumin seeds, red chili powder, ginger, and turmeric. Premium versions often highlight the absence of artificial colors or preservatives.
Usage: It is versatile and used as a dip for snacks like samosas, pakoras, or bhajis, as a spread for sandwiches, or paired with roti/parathas.
Nutritional Value: Guava is high in Vitamin C and fiber, making this a, in some contexts, healthier alternative to sugary jams.
