Gluten is a hot topic these days, but most people aren’t really sure what it is.
Gluten is a protein found in wheat, rye and barley. It makes bread chewy and helps hold the bubbles that yeast makes in dough so that it can rise. (Here’s a fun yeast experiment!) Although some people have a disorder called celiac disease which impedes them from digesting gluten properly, most people can eat it without any problem.
You can easily extract a ball of gluten from flour using nothing but your hands and cold water, to see for yourself what this stretchy grain protein looks like. Just add a cup of water to a cup of flour, mix it together and knead it for about 5 minutes. (Add more flour if it’s too sticky to handle.)
Now, put the dough under COLD water and start “washing” out the carbohydrates so that mostly the gluten remains. Your hands will freeze, so you may need to take a break. If you keep going until the water coming off the dough is mostly clear, you’ll be left with a gluten ball.
Some types of flour have more gluten than others, and sometimes extra gluten is added to pizza dough to make it chewier! Try this with several types of flour to see what has the most gluten (or no gluten.)
