Why make your own tomato paste? Tomato paste is a pantry staple used in a variety of recipes, from soups and sauces to marinades and stews. Making your own paste means you can use garden-fresh tomatoes at their peak and avoid the metallic taste that some store-bought cans have. Plus, it's a great way to reduce waste and save money in the long run!

Ingredients:

• 10 pounds of ripe tomatoes

• Salt (to taste)

• Herbs like basil or oregano (optional, for added flavor)

• Bottled lemon juice

Equipment:

• Large pot

• Food mill or blender

• Canning jars and lids (4-ounce jars)

• Large spoon

• Ladle

• Water bath canner

Step 1: Prepare the Tomatoes Start by washing your tomatoes thoroughly. Cut them into quarters and remove any stems and cores. Some people prefer to remove the skins and seeds by blanching the tomatoes and peeling them, but this is optional.

Step 2: Cook Down the Tomatoes Place the tomatoes on a cookie sheet and warm them in a 180 degree (356 f) oven until they are completely softened. About an hour. Check them often and prevent them browning by occasionally stiring them around.

Step 3: Puree the Tomatoes Once the tomatoes are softened, pass them through a food mill or blend them until smooth. This will also help remove any remaining skins and seeds.

Step 4: Concentrate the Tomato Paste Return the pureed tomatoes to the cookie sheet. Spread the paste evenly on the sheet and put it back in the oven. This step takes about 1 hour. Check and mix ( and re-flatten it on the sheet) the puré about every 20 minutes You really don't want the paste to start to stick to the sheet. Cook until thick enough to mound on a spoon.

Step 5: Prepare the Jars While the paste is cooking, clean your canning jars, lids, and rings.

Step 6: Can the Tomato Paste Ladle the hot tomato paste into the clean jars, add 1/2 table spoon of bottled lemon juice to each jar and mix well. Leave 1/2-inch headspace. Wipe the rims with a clean cloth, apply the lids, and tighten the rings.

Step 7: Process the Jars Place the filled jars in a water bath canner and cover them with hot water. Bring to a boil and process for 45 minutes (adjust time for altitude). Remove the jars and allow them to cool on a cloth-covered surface.

Step 8: Store Your Tomato Paste Check that the lids have sealed properly – they should not flex when pressed. Label your jars with the date and store in a cool, dark place. Properly canned tomato paste can last for up to a year.
