Instructions

Prepare the tomatoes

Wash the tomatoes thoroughly. Remove any stems and blemishes.

Pro tip: Use a paring knife to carefully remove any spots.

Blanch the tomatoes

Blanch the tomatoes by placing them in boiling water for 60 seconds, then immediately transfer to an ice water bath to cool.

Pro tip: Blanching loosens the skins for easier peeling.

Peel the tomatoes

Once cooled, peel the skins off the tomatoes. They should slip off easily after blanching.

Pro tip: Use a small knife to help with stubborn areas.

Prepare the jars

Sterilize your canning jars and lids by boiling them in water for at least 10 minutes. Keep them hot until ready to use.

Pro tip: Hot jars prevent thermal shock when adding hot contents.

Fill the jars

Add 1 tablespoon of lemon juice to each jar. Pack the peeled tomatoes into the jars, leaving 1 cm (1/2 inch) headspace. Add salt if desired.

Pro tip: Press down gently to remove air bubbles.

Seal and process the jars

Wipe the rims of the jars with a clean cloth. Place lids and screw bands on until fingertip tight. Process in boiling water bath for 45 minutes.

Pro tip: Ensure jars are fully submerged.
