Fat Crystallization
Fat Crystallization is a fundamental process in pastry making where fats (like butter, chocolate, or specialty baking fats) are carefully managed to create the right texture in baked goods and confections. It's similar to how ice forms in specific patterns - the fats in pastries need to form the right pattern to make things like chocolate snap properly or croissants be flaky. Pastry chefs control this process through specific temperature and mixing techniques. This skill is especially important when working with chocolate, laminated pastries (like croissants), and buttercream preparations.
