Hi Monica,
Thank you for your feedback and we're sorry to hear that you've been experiencing inconsistent results with certain recipes like your pineapple upside down cake and steam roasted veggies.
Regarding the Pineapple Upside Down cake, after the first 15 minutes of baking, gently open the lid to vent the steam, then wipe off any moisture on the inside of the lid using a clean cloth or paper towel. Once done, close the lid and continue baking for the remaining time. This step helps the cake finish baking with a better texture. Please try the above and see if it cooks to the desired amount.
Since you also mentioned that the potatoes were slightly undercooked when preparing the Steam-Roasted Vegetables recipe, we recommend making slight adjustments to the cooking time to ensure they are cooked through to your desired result.
If the steps above do not resolve the issue, the pot may have developed a buildup of residue and may require a more thorough cleaning. When the Musui has accumulated significant staining or residue, it can become more prone to food sticking and may not distribute heat as evenly as intended. For all stains for the Musui, we recommend using Bar Keeper’s Friend Soft Cleanser (liquid type) and scrubbing with balled-up plastic wrap or a soft sponge. Plastic wrap tends to work best because it doesn’t absorb the cleanser.
If you have any questions or would like further support regarding the above, please reach out to us at support@vermicular.us with details about your cooking process, including heat settings and any other specifics about how you're preparing these dishes. Our team would be happy to work with you to identify what might be causing the inconsistency and help you achieve better results.
