You'll need flour, sugar, baking soda, salt (regular table salt and coarse salt), active dry yeast, and butter (or margarine). This recipe makes a lot of pretzels, so feel free to half the recipe if you don't want that many. You can however freeze the extra pretzels and microwave them later. They are quite tasty and much cheaper than the store-bought ones.
Step 2: Yeast
Mix 3 packets of active dry yeast, and 2 teaspoons of sugar into 2 and 1/2 cups of very warm water. Mix until all is dissolved and set to the side while you get everything else together. It will start getting bubbly. Don't worry. It's supposed to. And yes, it has a very yeasty aroma. That's ok too.
Step 3: Everything Else
Go ahead and start melting 5 tablespoons of butter or margarine, but don't add it yet. Put 9 cups of all-purpose flour in a large bowl. Of course a flour war may ensue if you have helpers, but try to at least get what you need in the bowl first. Then add a cup of sugar and 3 teaspoons of salt. Blend well.
