Set a pan on medium heat, add butter, crushed bay leaves, minced garlic, and minced ginger. Saute for a minute.
Add sliced or chopped onions and saute for 1-2 minutes.
Add sliced or chopped beetroot and saute for another minute.
Add finely chopped fresh tomatoes, crushed black pepper, salt, dried basil, and sugar. Mix and mash well.
Add water and stir well. Cover and boil for 12-15 minutes for veggies to cook well. Allow to slightly cool before straining.
Meanwhile in a bowl add corn flour, and water and stir well using a spoon to make lump-free slurry.
Strain the soup mixture into another pan using a sieve and press down the pulp using a spoon or spatula to extract the liquid.
