Gajar ka halwa is a very authentic, famous, delicious Indian sweet. It can be made in any occasion and served warm or at room temperature. I have prepared Gajar ka halwa, without using Mewa or khoya. Khoya or Mewa is used to enhance richness and flavour in sweets. When I was making gajar ka halwa, I prepared beetroot halwa, can view in the picture. Preparation method is the same but taste and colour differs. Can use any nuts like almonds or pistachios as per your taste. Gajar ka halwa is cooked in milk, by thickening it on lower flame or medium flame, by stirring it continuously, so that it does not stick to the bottom. So it is cooked at low flame, but in between can cook at medium flame.
