• 250 g mushrooms
• 500 g chickenfilet or beef
• 600 ml chicken or beef stock
• 1/2 tbsp lemonjuice
• Fresh parsley
• 50g Butter
• 70g flour
• 10 ml cooking cream
• White and/or black pepper
• Salt
• (optional; usually when using chicken): 250g minced veal
• (optional) 1 eggyoke
• (optional) 2 tbsp breadcrumbs

For the meat:

• Cut the meat in small cubes (about 2cm²)
• Start cooking the stock, cook the beef/chicken.
• Note: that with beef this will need about 2 hours, so its smart to prepare this beforehand). The matter a fact, you can just get water, and prepare a stock using the meat and adding some basic vegetables you would normally use for stock, and use that stock for this dish.
• When done, seperate the meat from the vegetables and the stock. We wont need the vegetables from the stock for this dish. They can always be used in creative ways ;)

For the Meatballs (optional):

• Mix the minced veal with the eggyoke and the breadcrumbs.
• Roll small balls and poach these in the chickenstock.
• When done, keep them apart.

Prepare the shrooms:

• Sauté the mushrooms shortly in butter, making sure that most internal moisture is vaporized.
• Quench with lemon juice.

For the bechamelsauce:

• Make sure the stock is on a reasonable tempurature (nice and hot, else the mixture will cool to abrubtly)
• Melt the butter, add the flower and mix properly with a wooden spoon.
• Don't forget to stir every now and again. Wait until the flour is done, which you will notice by smelling somewhat of a cookie-smell.
• Take the pan of the fire. = Gently and gradually add the stock one ladle at a time, mixing it into the flower butter mixture.
• If all stock is mixed in, put it back on the fire and bring it to a boil. Keep mixing it with a whisk until you have a nice and smooth sauce.
• Season with pepper and salt.

Final Preparation:

• Having the bechamelsauce from the previous step, we add the meat, the mushrooms and optionally the veal meatballs.
• Finely chop the parsley and add it aswell.
• Optionally season with pepper, salt, and lemonjuice.
