gluten-free eats

Adam Ragusea aragusea was a public radio reporter, is now a journalism professor, and has recently become a YouTuber talking about home cooking with a healthy dose of science. I was thrilled by last year’s Alternative Starches: How to thicken sauces without flour. He demonstrates making gravy with

• flours: rice, potato, and corn (US: corn starch)
• starches: tapioca, arrowroot
• gums: xanthan and agar agar.

He also explores how some gums maintain their staying power at all temperatures, which finally explained why wheat flours sometimes show up in ice creams.
