Sometime back when we make any kurma or even a simple curry, I simply used to chop it finely and add. These days when the boys not wanting to have the tomato skin in the gravy, I have resorted to making a puree and adding to the gravy. This makes sure that you have a thicker and more gravy.
When you want to blanch tomatoes, take ripe tomatoes, wash and keep it aside.
Bring to boil 1 -2 cups of water as required. When the water is boiling, make sharp slits on the tomatoes and add to the boiling water. Switch off the flame and keep it covered. This takes about 5 mins for the skin to loosen up.
Typical blanching would require the tomatoes immersed in hot water to be immediately immersed in cold water. But I have seen that it works just fine, if I leave it in hot water and cool and puree to use in gravy.
Remove the skin with a knife and allow to cool. Puree the tomatoes and use in the gravies.
Used in kurmas, gravies where you want more gravies.
Smoking the tomatoes:
Wash and pat dry the tomatoes. Using a fork, insert into the tomatoes. Show over flame and roll over the tomatoes so that the tomatoes get burnt. When the tomatoes are done all over, remove from the fork and allow it to cool. Remove the skin when the tomatoes cool.
This gives a wonderful tastes for foods like Paneer Tikka, Baigan ka barta etc.
When you have excess tomatoes on hand, you can puree as many as you want either by blanching or my simply pulsing it and storing it in ice trays. Once the tomatoes are frozen you can break and store them in zip lock covers and use when required.
