"Useless for porridge but fine for soup" star star star star star_border The bowl is too small for porridge, it bubbles up and ends up all over the microwave and dripping down the exterior of the bowl. Works fine for heating up soup though and is leak proof when transporting the contents. Would have given it 5 stars if you could actually cook porridge in it. Fiona Maccoll - 19 February 2021 support_agent A note from the team Thank you for your review. We'd recommend stirring the porridge part way through the cooking time.You could try cooking for longer on a lower temperature. we're pleased you find it works well for heating up soup.
