Yes, tempering is useful in Western cooking, particularly in chocolate work, sauce making (like custards and hollandaise), and even in some baking applications to prevent curdling or ensure a smooth texture.
Tempering, in the context of cooking, refers to gradually raising the temperature of a delicate ingredient, like eggs or chocolate, by slowly introducing a hot liquid. This prevents shocking the ingredient and causing it to seize, curdle, or otherwise become unusable.
Here's how it works in different Western cooking methods:
Chocolate: Tempering chocolate involves heating and cooling it to specific temperatures to stabilize the cocoa butter crystals. This results in a glossy, snap-able finish, preventing bloom (the white streaks that appear on poorly tempered chocolate).
Custards and Sauces: When making custards, sauces like hollandaise or pastry cream, or even certain soups, tempering prevents the eggs from scrambling when added to hot liquids. A small amount of the hot liquid is whisked into the eggs to gradually raise their temperature before adding the warmed egg mixture back into the main pot.
Baking: While less common, tempering can be useful when incorporating cold ingredients into a warm batter, especially if the batter contains ingredients prone to seizing, like melted chocolate.
When tempering eggs, add the hot liquid to the eggs *very* slowly while whisking constantly and vigorously. This ensures even heat distribution and prevents localized cooking. A steady stream is better than a large pour.
