Allulose blends most like sugar and caramelizes gently. Erythritol also works, though it will not brown as much. Both are suitable for diabetics when used in moderation. - What oil is best for air frying if I cannot use olive oil? Avocado oil is a great neutral, high smoke point option that keeps flavors clean and supports heart-healthy fats.
