There are several types of oats, but the most common ones are:
- Rolled oats (old-fashioned oats): These are the most commonly used for oatmeal and cook relatively quickly (about 5 minutes).
- Steel-cut oats: These are whole oat groats chopped into pieces. They take longer to cook (about 20-30 minutes) and have a chewier texture.
- Quick oats: These are rolled oats that have been pre-cooked and then flattened further, so they cook very quickly (about 2-3 minutes).
