Fresh Tomatoes - I used a mix of home grown grape and cherry tomatoes
Most recipes of tomato paste call for removing the skin and the seeds. Since I am using home grown cherry tomatoes here, I decided to use my vitamix blender to blend the tomatoes with the skin and seeds to make a smooth mixture.
Cook this mixture over stove top for a couple of hours over medium low heat. Stir frequently towards the end. Once most of the liquid has evaporated and the paste looks dry and starts sticking to the bottom of the pan, add olive oil. Mix well and cool completely. Store in a glass jar in the refrigerator and use as required.
