Bechamel Sauce

Just the normal white sauce but instead of plain soya milk :

Take small raw onion, scraped carrot, celery stick, a bay leaf, parsley stalks and a spring of thyme put them in a pan with the soya milk. Bring to the boil, remove the heat and leave covered for 15mins so the flavour infuses into the milk.

Use as soya milk in white sauce.

White Sauce

2 tablespoons nice oil (soya, walnut, sesame etc.)
25g sauce flour or just plain flour
300ml soya milk
salt & pepper
bit o'nutmeg

Warm the oil, add the flour, give it stir & take the lumps out but don't let the flour brown.
Add third of the milk, stir until it thickens, repeat until you have no milk.
Making it thinner is easier than making it thicker because of lumps.
Gently heat it for 10 minutes to cook the flour.
