1 cup beef stock
1 cup heavy cream (milk works just fine)
3 Tbsp flour
1 tsp soy sauce
1 tsp pepper
1/2 tsp dried rosemary
Whisk together all the ingredients in a medium sized pot. Cook and stir over low-medium heat until thickened (about 10 minutes), stirring occasionally. Poor over your favourite meatballs and mashed potatoes.
For this recipe I use a half of a beef stock cube dissolved in a cup of water. I don't like opening a box of beef stock if I don't have a use for the leftovers. I also use 1% milk because that's what I always have on hand.
