How to Fix Lumpy Béchamel Sauce?

Lumpy béchamel or Turkish milk pudding may be improved by whisking or passing it through a fine sieve; the result depends on the size of the lumps and the condition of the mixture. If using a blender, check the manufacturer's instructions to confirm that both the appliance and its container are suitable for hot mixtures. Do not put hot mixtures in sealed personal blender cups. Removing lumps changes texture only; it does not make a spoiled or improperly stored mixture safe.

How to Fix Lumpy Béchamel or Turkish Milk Pudding
Take the pan off the heat and whisk without splashing. If necessary, use a heat-resistant fine sieve to remove lumps. If the mixture is too thick, you can add 1–2 tablespoons of warm milk, taking the recipe's intended consistency into account. If a blender is an option, follow only the manufacturer's temperature, filling, lid and operating instructions for that mixture and container; do not assume that waiting a few minutes alone makes the temperature safe. Do not use an appliance that is unsuitable for hot liquids.

Common Mistakes When Making Béchamel and Turkish Milk Pudding
Heating flour or starch before it is dispersed sufficiently in the liquid can cause lumps. Adding the liquid all at once and neglecting to stir can also make a smooth consistency harder to achieve. Excessive heat can cause sticking on the bottom. Combine ingredients in the order given in the recipe, control the heat and stir along the bottom and sides of the pan.

How to Prevent Lumps in Béchamel and Turkish Milk Pudding
For béchamel, one method is to add milk gradually to a roux made with butter and flour, whisking after each addition. For starch-thickened milk pudding, you can first mix the starch smoothly with a little cold liquid before adding it to the remaining liquid in the recipe. These are different methods; not every flour-based mixture needs to begin with a cold slurry. Adjust the cooking time and consistency to the recipe. Regular stirring can reduce lumps but does not guarantee a perfect result in every mixture.
