Wash and dry the tomatoes

Cut the tomatoes in half. Core and seed the tomatoes. 

Place the tomatoes in a large pot filled with water. 

Bring the pot to a boil.

Reduce the heat and simmer for 15 minutes.

Remove the tomatoes from the hot water carefully, and place them in a bowl of cold water. 

After the tomatoes are cool, peel the skin off and discard.

Add the peeled tomatoes to a blender.

Blend until smooth.

Now you can use or store your fresh tomato purée.
