Take tomatoes and make a criss cross pattern on it.

Boil lots of water, drop tomatoes in and blanch it for 45 sec to 1 min. Drain it and immerse it in cold water. Now the skin will just peel off.

Now chop it roughly and puree it.

Pass it through a sieve.

Pour it in a sauce pan and boil it and reduce till it reaches the right consistency. Add salt vinegar.

You can store this in a air tight container in fridge for upto a week or freeze it in individual icecube tray. Once frozen collect them in a ziploc bag or a freezer container.

For tomato paste, reduce the tomato puree further till it gets thick jam like texture. Cool it and store it in a air tight container in fridge.

Notes:

1)You can store this in a air tight container in fridge for upto a week.

For storing it for many months. Freeze it in individual icecube tray. Once frozen collect them in a ziploc bag or a freezer container. This can be store in freezer for more than a year.

3)The tomato paste keeps well in fridge for more than a month. Make sure you evaporate all the water from the tomato puree and it should be very thick and paste like.
