Ketchup

Ketchup - The #1 condiment around here, followed closely by honey mustard but that's another post.  Why make it yourself?  The store bought stuff is LOADED with high fructose corn syrup and "natural and artificial" flavorings.  The stuff you make at home has 6 ingredients and is super easy.
Here is what you need to get started -

28oz can of whole tomatoes
1 Medium onion - chopped
2 Tbsp olive oil
1 Tbsp tomato paste
1/3 cup dark brown sugar
1/2 cup cider vinegar
1/2 tsp salt

Puree tomatoes in a blender and add to a large pot - You want high sides so when it is simmering it doesn't go all over your stove.

Add olive oil and onions to a small saute pan and cook over medium heat for 5 minutes.  Add to tomato puree.

 Bring to a low simmer and allow to simmer uncovered for 1 hour until thickened.

Put back into the blender - be careful its very hot!  Puree until smooth (vent lid to let the steam out)

 Store covered in the fridge for about a month - if you can make it last that long.

To much work you say?  No problem - instead of simmering on the stove put it in the crock pot and leave the lid off.  Low for 4-6 hours will do the same thing.
