Peel and finely chop the onions and garlic. Gently simmer milk, butter, onions, garlic, bay leaf and a little nutmeg in a saucepan for about 30 minutes. Let the mixture cool down (let the original soak overnight!)
Roughly chop the walnuts. Cut the crust off the bread. Cut the bread into pieces. Set aside some bread and some walnuts. Remove laurel from the milk. Bring milk to the boil again, add bread and walnuts, bring to the boil again
Puree the mixture very finely, dilute with a little milk if necessary, season with salt, pepper and possibly nutmeg. Cut the rest of the bread into small cubes or pieces, roast it together with the walnuts in a pan without fat until light brown. If necessary, heat the sauce again, arrange in a bowl and sprinkle with the nut-bread mixture
