Their favorite boiled supper dish that they ate every day and what type of writing is this?

This is a fragment of a sentence that is missing context and information. To understand what type of writing this is, we need more information, such as:

* Who is "they"? Are they a family, a group of friends, a specific historical figure?

* What is the context? Is this part of a story, an essay, a blog post, a recipe?

* What is the purpose of the writing? Is it meant to be informative, descriptive, persuasive, or entertaining?

Without this information, it's impossible to determine the type of writing.

Here are some possibilities based on different contexts:

* Story: This could be part of a description of a character's daily routine or a flashback to a specific time period.

* Essay: This could be part of a personal essay about a favorite food or a cultural tradition.

* Blog post: This could be part of a food blog post about simple and healthy meals.

* Recipe: This could be the introduction to a recipe for a boiled supper dish.
