<s>[INST] I was planning on buying a nice sweet potato casserole for Thanksgiving dinner from a local grocery store. But then I realized that they had nothing but frozen and pre-made sweet potato casseroles. As a result, I wanted to try making a homemade sweet potato casserole and bring it to Thanksgiving dinner.

Here's my problem: I have a tendancy to over buy ingredients for recipes. I buy everything necessary and some "just in case" extras. For example, I recently over bought flour, sugar and marshmallows. I am now stuck with an excess of these ingredients after making a granite and s'mores themed dessert. 

To prevent over buying, I'd like to know what specific measurements of ingredients are needed for a simple sweet potato casserole recipe. Here's my attempt at a simple sweet potato casserole recipe:

Ingredients: 
- Sweet Potatoes
- Brown Sugar
- Cinnamon 
- Salt 
- Butter 
- Marshmallows 
- Almonds (for garnish)
- All Purpose Flour 

Instructions: 
1. Preheat Oven to 350, 
2. Peel and boil the sweet potatoes.
3. Bake at 350 with butter, brown sugar, cinnamon and salt.
4. Sprinkle marshmallows on top. 

However, I only have a loose idea of the quantities needed for each ingredient. 

What are the exact quantities for the ingredients for a simple sweet potato casserole recipe?[/INST]
