Which of the following relates to section J?

The correct choice pertains specifically to the focus area of section J, which is primarily concerned with puddings and various types of desserts. This section typically includes recipes, techniques for preparation, and the characteristics of different puddings as well as other dessert types. Puddings can encompass a range of preparations, from classic custard-style puddings to fruit-based desserts and beyond, which allows for a rich exploration of texture and flavor.

In contrast, the other options cover different categories of baked goods and desserts. Pastry and pies focus on crusts and the specific techniques used in pastry-making, which is a distinct culinary skill set. Cakes, fillings, and frosting delve into the art of cake baking and decoration, emphasizing different methods and styles. Breads and sweet doughs cover yeast-leavened products and sweet bread variations, which are entirely different from puddings. Each of these areas has its unique set of skills and applications, which is why the focus of section J specifically highlights puddings and similar desserts.
