Don’t get impatient with this step. It builds the flavor.
Add the sugar if using, stir to mix and sweat a further 3 to 5 minutes. Add the turmeric, stir to mix and cook for 1 minute. Add the tomatoes bring to a simmer and cook for 5 minutes. Add water to cover. The more water you add, the thinner the soup will be.
