Quantity : 625 ml
Preparation : 10 min 

Cooking : 20 min

Ingredients

1 2/3 cup canned tomatoes (diced) 400 g
1 clove garlic
1/2 onions, finely chopped 100 g
1/2 carrots, finely chopped 50 g
1/4 stalk celery, finely chopped 18 g
1 tbsp olive oil 15 mL
1 1/2 tbsp butter, unsalted 20 g
1/2 tsp salt 2 g
1/4 tsp ground pepper 1 g

Before you start

A food processor to chop the vegetables and a pressure cooker to reduce the cooking time would make things easier with this recipe.

Method

Finely chop the onion, carrot, celery, and garlic.

Heat the oil and butter in the pressure cooker or in a saucepan over low heat. Add the chopped vegetables. Cook 4-5 min, stirring a few times: the vegetables must soften without burning. Add the diced tomatoes, salt and pepper to taste.

If you are using a pressure cooker, cover, close, and bring to high pressure. Cook 15 min from the time it starts to spatter. (Follow the manufacturer's directions to determine when high pressure has been reached). If you are not using a pressure cooker, simmer, covered, for about 45 min.

Observations

This sauce can be stored up to 2 weeks in the refrigerator. Freeze larger quantities.
