If your porridge is boiling rather than simmering, turn the heat down and remove the saucepan from the heat for a moment to let the mixture cool. You don't want your porridge to boil for too long as this could burn the oats and cause them to stick to the bottom of the saucepan. We recommend using a nonstick saucepan, preferably copper-lined, as this will ensure that the oats heat quickly without overheating or sticking to the surface. Since you can’t add butter or oil to the porridge, you can only stop the food from sticking by keeping the heat at a manageable level.
