Beef steak tartare with Golden Delicious and walnuts

Dice the cleaned fillet of beef (do not chop) and place in a bowl.

Then dice the shallots.

blanch the shallots three times in boiling water. This means: put the diced shallots in water, bring to a boil for 10 seconds, strain and rinse under cold water. Repeat this procedure a total of three times. This eliminates the bitter substances.

Then cut the basil into fine strips and mix with the mustard, shallots and beef. 

Then hollow out the inside of the apples and finely chop the pulp of the apples and add to the tartare. 

Finally, season the tartare with salt, pepper and olive oil and garnish with the walnuts.
