This is a take on a traditional demi-glace without needing to buy an astronomically large amount of veal bones. Use this as your main base for pan sauces, an extra flavor bomb, or a replacement for recipes that call for broth or stock.
These are the basic proportions — multiply as needed. I typically multiply by six to give me several weeks worth of demi-glace ice cubes.
Ingredients
- 1 qt (32 oz, 946mL) low-sodium broth or stock (I prefer Pacific Foods)
 - 1 1/4 oz (7g) packet unflavored, unsweetened gelatin
 - 1 teaspoon (5mL) tomato paste
 - 1 teaspoon (5mL) low-sodium soy sauce
 - 1/2 teaspoon onion powder (very optional)
 
Directions
- Put the tomato paste in a large pot, then turn the heat on medium
 - Spread the paste around the bottom of the pot and stir until it just barely starts to brown
 - Deglaze with the broth
 - Stir in all other ingredients and boil over high heat until reduced to about 1/6th of its original volume
 - Freeze in ice cub trays
