Vegan Savoury Sauce - cooking recipe

Ingredients

1/2 medium onion, finely chopped
5 large button mushrooms, finely sliced
1 tablespoon sunflower oil
1 cup unsweetened soymilk
1/3 teaspoon sea salt
2/3 teaspoon cornflour (maize flour)

Preparation

Fry onion in oil until soft, not brown. Add mushrooms and fry all until browned.
In a separate jug, mix corn flour with two tablespoons of the milk.
Slowly add the rest of the milk trying to avoid lumps.
When smooth pour into saucepan with the onions and mushrooms.
Keep the heat very low stirring (or whisking) steadily until thickened (don't let it thicken too quickly - give the flavours time to blend).
Add salt to taste.
