Tomato Paste RecipeBasically tomato paste is tomato that has been reduced, reduced again, and then reduced some more! It's ideal to make on a cold day over the gentle heat of a coal range.
First score a cross on the bottom of each tomato using a sharp knife. Blanch the tomatoes in boiling water, then drop into ice cold water. After this the tomato peel should almost fall off. Pull the remaining peel off the tomatoes. Cut the core out and remove all the seeds. I keep the peelings for making homemade stock and the seeds for adding into stews etc. Chop the flesh and measure what you're left with which would normally be around 4 litres. Add ½ teaspoon of salt to each litre. Place the tomato and salt in a large pot and simmer over a low heat for around 1 hour, stiring often to prevent any catching and burning. Remove from the heat and press through a fine sieve or process through a food mill. Return the tomatoes to the pot and continue to cook very slowly until the paste holds its shape on a spoon, approximately 2 to 3 hours. Stir occasionally to prevent any sticking.
Spoon into hot sterilized jars, leaving 3cm (1 in) at the top. Slop on a little olive oil to cover and seal. Ensure the lids have vacuum sealed, or the paste will spoil. Alternatively you can fill and freeze ice cube trays and free flow cubes of paste in freezer bags for use later.
