For 30 portions

Ingredients

3.5 kg ripe tomatoes
4 large onions
2 large heads of garlic
1 dl olive oil
2 tablespoons sea salt
2 tablespoons sugar
1 teaspoon freshly ground pepper
1 sachet of Italian herb mix (or a mix of basil, oregano, marjoram)

Preparation procedure

Vegetable preparation Wash the tomatoes and cut into quarters. Peel the onions and chop coarsely, leave the garlic whole.
Seasoning and layering In a deep baking dish mix the tomatoes, onions, whole garlic cloves, oil, salt, sugar, pepper and herbs. Gently stir.
Slow baking Place the baking dish into a preheated oven at 200 °C. Bake for 2 h; after the first hour stir the contents so the vegetables brown evenly and caramelize slightly.
Blending and seasoning Blend the baked mixture with an immersion blender directly in the baking dish, or transfer to a pot. Bring to a gentle boil and adjust to taste with salt, sugar or herbs.
Sterile filling Pour the hot sauce into clean, boiled jars. Immediately seal with lids, turn them upside down and wrap in a blanket. Let cool in an upright position for 1–2 hours.
Storage After cooling store in a cool, dark place. Consume within 6 months.
