The amount of milk required to make 1 kg of khoa, also known as mawa or khoya, depends on the moisture content and the specific process used to make khoa. Khoa is a milk solid widely used in Indian sweets and dishes. On average, it takes about 4 to 5 liters of milk to produce 1 kg of khoa.
The process of making khoa involves simmering and reducing milk until most of the moisture has evaporated, leaving behind the concentrated milk solids. The exact quantity of milk required may vary based on the method of preparation, the desired consistency of khoa, and the moisture content in the milk used.
Keep in mind that khoa can be made with different levels of moisture, resulting in variations like soft khoa (chikna), firm khoa (danedaar), or hard khoa (battisa). Each type of khoa requires a different amount of milk and cooking time to achieve the desired texture and moisture level.
