Add the tomatoes to the pot and let them simmer for 30-60 seconds (you might need to do this in batches).
Meanwhile prepare a big bowl with ice cold water.
Drain the tomatoes from the simmering water and immediately add to the ice cold water. Let them cool for a short while.
Peel tomatoes, cut in half or quarters and deseed them.
Add tomatoes and garlic cloves to an oven safe baking pan, followed by lemon zest, honey, sea salt, black pepper and a little bit of olive oil. Do not use too much, they should not be swimming in olive oil. Stir to combine.

Meanwhile add balsamic vinegar to a small pot, bring to a boil, reduce and let it simmer on low heat for 10-15 minutes, until it has reduced and thickened. Set aside.
