Classic smoked BBQ tomato sauce

Much more than ketchup: grilled tomatoes provide the smoky base for this sauce. The heat concentrates the tomato flavour, evaporates excess water, and caramelises sugars. This is a true 'from scratch' BBQ experience.

Instructions

1

Cut the tomatoes in half, brush cut sides with oil, and place cut-side down on the hot grill. Cook for 5-8 minutes until they start to char.

Tip: This char provides the smoky flavour.
2

Meanwhile, sauté the chopped onion and garlic in oil in a pan until translucent.

Tip: Do not brown, just soften.
3

Add the grilled tomatoes to the onions (with or without skin), add the other ingredients (vinegar, sugar, sauce, spices).

Tip: The juice of the tomato will provide the liquid.
4

Cook over medium heat for 10 minutes until thickened.

Tip: Flavours concentrate with evaporation.
5

Blend until smooth with a stick blender. Dilute with a little water if too thick.

Tip: Be careful with hot splashing sauce!
