The butter or drippings should be heated in a big pan. For about three to four minutes, cook the garlic and onion. One minute later, add the flour and stir.
Red wine should be added to the concoction. Regularly whisk to avoid clots. For about two minutes, simmer the combination.
Pour in the meat broth. Simmer for an additional two to three minutes until slightly thickened.
The remaining components should be added to a mixing bowl and thoroughly combined.
Once more, bring the liquid to a boil. For 15 minutes, simmer the food in the saucepan with the lid on. The procedure is finished once the liquid begins to reduce.
To flavor, add salt and pepper. Strain the liquid by pouring it into a strainer. It is best to serve it right away or keep it chilled. Enjoy!
