Delicious Homemade Baguette

Step 4: Making the dough

I find this the perfect time to add the salt to the sponge (soon to be dough)

Mix in the 2 teaspoons of salt.

Then, if using a kitchen aide, use the dough hook to mix in the remaining 1.5 cups of flour.
If you are using a spoon, you can use the spoon or your hands to mix in the remaining 1.5 cups of flour.

KNEAD!!! (really only necessary if you are using the spoon method)
If you are using the stand mixer, you can just keep the dough hook running through the dough a bit longer.

Add extra flour when kneading or using the dough hook. I added probably somewhere around 2/5 of a cup. 

When it is first rising, the dough will seem very unwilling to stick together... DON'T worry, after the first rise this won't be an issue.
