By default, Family Cookbook Project may arrange recipes to make efficient use of page space. That can help reduce unnecessary blank areas and keep the finished cookbook compact.
If you want a different order, use the recipe sorting options in your editor tools. Depending on your cookbook setup, you can organize recipes alphabetically, by contributor, by category, or using the available custom sorting choices.
After changing the sort order, preview the cookbook again. A different order can change where recipes break across pages and may increase or decrease the total page count.
