Begin by massaging baking soda into your beef strips until each piece is coated.

Mix in salt, pepper, and cornflour, ensuring the beef is well-coated.

Heat some olive oil in a pan and toss in your beef, sizzling until it’s beautifully browned.

Pour that tempting white wine in and give the pan’s bottom a good scrape – we’re talking flavor central!

Time for garlic, mustard, and tomato paste! Mix ‘em in well.

Add mushrooms 🍄, stir, and let those flavors meld.

In goes the beef stock and sour cream. Keep stirring until that sauce gets thick and dreamy.

Finish with a sprinkle of parsley 🌱 and give one last stir.

Voilà! Serve it atop rice, pasta, or mash, and let your taste buds do the happy dance! 💃
