Practical
Consumer tips
- 1
If buying Barley, choose hulled over pearled. Pearled Barley cooks faster but loses the bran where most fiber and nutrients live.
- 2
Reduce arsenic in Red Rice by rinsing it well and cooking it in a 6:1 water ratio, draining the excess like pasta.
- 3
Introduce Barley slowly into your diet to give your gut time to adjust to the high fiber and avoid bloating.
- 4
Both grains freeze beautifully after cooking. Make a large batch and portion them out for quick, healthy weeknight dinners.
