Beef on a cushion of onion puree

Good evening, dear friends . I wanted to share with you an interesting and fairly simple beef recipe, in Thai style. A couple of years ago, on one corporate, met a chef from Thailand, drank, all -walk, tequila, gin, all together. In the morning, on a hang-over, our Thai friend, has prepared for us this smart dish.
Thanks to a special roast, the meat turns spicy and very delicate. And the vegetables perfectly complement the taste of the dish.
Ingredients:

• Beef tenderloin, or flank steak -150 grams
  

• Celery - 20 grams
  

• Bulgarian pepper - 30 grams
  

• Shallot onion - 30 grams
  

• Chili pepper - 3 grams

• Zira - 2gram

• Oyster Sauce- 15grams

• Onion puree -100 grams

• Butter - 5 grams
  

  COOKING STRATEGY
