Frying oil
If you’re in a rush, use 1.5L (6 cups) low-sodium beef or chicken broth. Simmer it 20–25 minutes with 1 onion, 1 carrot, 1 garlic clove, 1 bay leaf and 1 tbsp tomato paste to “fake” the roasted flavor. Strain, then continue with the gastrique and thickening exactly like below. Because store-bought broth is thinner, start with less liquid or add a bit more roux to reach your preferred thickness.
