Directions

• Prepare a large pot of boiling water. Meanwhile score the top and bottom of each tomato with a knife in an x.
• Prepare a ice water bath.
• Blanch the tomatoes until the scored skin begins to peel back, about 2 min, and quickly transfer to cold water.
• Peel and core the tomatoes (you can completely de-seed them if you wish)
• In a large pot mix tomatoes, sugar and zest. Bring to a boil and simmer for 3 hours, or until the consistency of a thick jam, skim surface regularly during this time.
