False trace

False trace looks like real trace: the batter thickens and may even hold a brief trail when drizzled, but the thickening is caused by hard oils or butters cooling and starting to solidify rather than by the batter actually saponifying enough to hold its structure. It is common in recipes with a high percentage of cocoa butter, shea butter, or other hard fats.

The distinction matters because a batch at false trace is not actually ready for the next step. If colorants, fragrance, or additives are stirred in, or the batter is poured, at false trace, it can behave unpredictably as the temperature evens out and the fats either resolidify further or loosen back up.

A common way to check is to gently warm the batter slightly, such as by placing the container in a warm water bath, and see if it thins back out. If it does, it was false trace rather than real trace. Rushing past this check and pouring anyway is a frequent cause of unexpectedly separated or textured bars.
