Frequently Asked Questions

Can I use steel-cut oats instead of rolled oats?▼

Yes, but steel-cut oats take longer to cook (25-30 minutes) and require a higher liquid ratio (3 cups of liquid per 1 cup of steel-cut oats).

Is ground flaxseed better than whole flaxseed?▼

Yes. Ground flaxseed is much easier for your body to digest and absorb the beneficial omega-3 fats and fibers.
