These are the supplies that are relatively inexpensive and will provide your sauce making operations with all the tools.

Strainers
You don’t necessarily have to strain your hot sauce but I do for different recipes. A good blender should be able to get a smooth consistency to your sauce.
I use two different sizes buy Cuisinart offers the 3 pack available here from Amazon.

Funnels
I use funnels primarily to pour sauce into the bottles when I have completed a recipe.
Get this set of 3 here from Amazon.

Pots & Pans
Any 4 quart or larger pot will work but you will want at least a three gallon or more for larger operation. I use WearEver for the durability but I don’t think brand will effect the outcome of your sauce.
