PTE Recipes:
The PTE Recipes section contains recipes from recipe or cooking challenges previously hosted by Plan to Eat. These recipes are available to you, even if you weren't involved in the original challenge.
The recipes in the challenge section are completely optional and will only be visible in your account if you choose to save them.
