Tomato powder is simply dehydrated tomatoes that has been finely ground. I find it very handy during off season or when tomatoes are not at their best. This powder provides the depth in flavor and I don't worry if I am short on tomatoes thanks to this.

Its a nutritional powerhouse boasting a rich source of vitamins A and C; minerals like folate, potassium, magnesium, and iron; protective antioxidants (lycopene) that is known to defend cells against damage caused by free radicals, and may reduce the risk for chronic diseases such as heart disease, stroke, and cancer.

Works great in rubs (think coating for tofu/paneer), thickening stews and soups, as a spice mix,in your dosa/idli batter etc. You can even use this powder to make tomato paste, tomato puree, pasta sauce - why even ketchup!
