Gradually add small amounts of warm broth or stock, stirring constantly, until the gravy reaches your desired consistency. If you don't have broth, use milk or water as a last resort, adding a touch of seasoning to compensate for any flavor dilution.
The key to thinning gravy without sacrificing flavor is to use a liquid that complements the existing flavors. Here's a step-by-step guide:
Heat the Gravy: Gently reheat the gravy over low heat. This makes it easier to incorporate the thinning liquid.
Choose Your Liquid: Ideally, use warm broth or stock (chicken, beef, vegetable, depending on the gravy's base). Warm liquid incorporates more smoothly than cold.
Add Gradually: Add the liquid one tablespoon at a time, stirring continuously. This prevents the gravy from becoming too thin too quickly.
Stir Vigorously: Use a whisk to ensure the liquid is fully incorporated and the gravy is smooth. This also helps break up any lumps.
Check Consistency: After each addition of liquid, check the consistency. The gravy should coat the back of a spoon without being overly thick or watery.
Adjust Seasoning: If you use water or milk, taste the gravy and adjust the seasoning as needed. A pinch of salt, pepper, or herbs can restore the flavor balance.
If your gravy is *really* thick and lumpy, try passing it through a fine-mesh sieve after thinning. This will remove any stubborn lumps and create a perfectly smooth texture.
