About this recipe (AI-generated; untested on the appliance)

These are original recipes created using AI on Crisp. They are not listed as official manufacturer recipes or recipes that have been verified using actual devices.

AI-generated content may contain errors. Flavor, texture, and reproducibility have not been verified using the actual appliance. Before cooking, read the conditions and checks in each step, and check the final result using the method described in the recipe.

Initial Heating Settings

First HeatingManual Settings200°C / 35min

After about 18 minutes, open the door and check to see if the cut surface is burnt. If it isn’t burnt, close the door and resume cooking; if it has started to burn, remove the food, then keep the door open and press and hold the On/Off button to turn off the power. When the set time has elapsed, insert a bamboo skewer into the thickest part of the food to check if it goes all the way through without strong resistance. If it does, transfer the food to a clean plate; if it’s still firm, remove it and proceed to the final check. If the food begins to burn, open the door to stop heating, remove the food using heat-resistant oven mitts and tongs, then keep the door open and press and hold the On/Off button to turn off the power. If you notice smoke, an unusual odor, or an error message, unplug the appliance, stop using it, and follow the instructions in the user manual.

Instructions for preheating, mid-cooking checks, and how to check for doneness are included in the preparation instructions.

The total time required, including preparation, has not been measured. The time shown is only the appliance's setting for the initial heating cycle.

Check Before Cooking
  • Select sweet potatoes with a diameter of 60mm or less at their thickest point, cut them in half lengthwise, and ensure the thickness from the cut surface is 30mm or less. Use sweet potatoes at room temperature and arrange them with the cut side facing up.
  • Place the wire rack in the middle rack position. Place the oil and crumb tray horizontally on the oven floor (below the lowest guide rail), and do not place food directly on the tray.
  • Do not preheat. Since the unit does not have a preheating function, set the temperature after placing the food inside the cold oven.
  • Adjusting Temperature and Time: With the power plug inserted into an outlet, press and hold the On/Off button to enter standby mode, then use the Menu button to select the menu option listed in the instructions. Use the Temperature button and the +/− buttons to set the temperature, and the Time button and the +/− buttons to set the time. Then, press the On/Off button to start. The power will turn off if there is no operation for 60 seconds while the unit is in standby mode, so be sure to load the food and close the door before entering standby mode.
  • To check on the food during cooking, open the door. Opening the door stops the heating process; closing it resumes it. Please close the door within 10 minutes. If the door is left open for more than 10 minutes, the power will turn off, and the cooking will not resume even if you close the door. If you need to stop the cooking midway due to burning or a malfunction, remove the food first, then keep the door open and press and hold the On/Off button to turn off the power.
  • Do not use the rotation function, rotisserie fork, rotating basket, aluminum foil, or parchment paper. Since the accessories and the oil and crumb tray will be very hot after cooking, handle them with heat-resistant oven mitts and tongs.
  • Before heating, arrange the specified amount per batch in a single layer with gaps between items and confirm that everything fits. If they do not all fit, do not start heating; instead, go to "Discuss these instructions" and specify the amount, number of items, and maximum thickness. Do not split the batch while keeping the original cooking time, nor adjust the time based on weight.

    Check the condition and finish cooking

    When the set time is up, insert a bamboo skewer into the thickest part to check if it goes all the way through to the center without much resistance. If it does, transfer it to a plate and eat it, being careful of the hot steam. If there is strong resistance, proceed to the final check.

    What to check if the food is not yet done

    If the dish does not meet the completion criteria, do not reheat it. Instead, go to “Discuss these instructions” and provide the total cooking time, the time the oven door was open, the quantity and thickness of the ingredients, and the condition of the center. For dishes that require a thermometer, please also provide the measured core temperature and the duration for which that temperature was maintained. Do not plate the dish as finished until it has been verified, and do not repeatedly add time without justification. If you need to interrupt cooking, transfer the food to a clean container and refrigerate it; when you resume cooking, ensure it is thoroughly reheated.

Check the results

Insert a bamboo skewer into the thickest part of the dish all the way to the center to check if it goes in without much resistance. If it hasn’t reached the desired doneness, do not reheat it; proceed to the final check. Be careful of the hot steam as you cut into it, and make sure it’s tender all the way to the center.

If you get stuck along the way

The center is still hard after 35 minutes

Remove it from the oven and proceed to the final check. The time required varies depending on the thickness of the potatoes, so we cannot guarantee that it will be ready in 35 minutes.

The cut surface burns

As soon as the food starts to burn, open the door and remove the food, then keep the door open and press and hold the On/Off button to turn off the power. Next time, spread an even thinner layer of oil on the cut surface.

How the Recipes Were Created and Sources Consulted
Standards verified in official documents
The default settings for the vegetable menu are 180℃ for 12 minutes; manual settings range from 50〜220℃ for 1〜60 minutes. There is no confirmed official setting for sweet potatoes.
Independently designed details and unverified points
These are unique conditions for a sweet potato weighing about 300g, halved lengthwise to a thickness of 30mm or less. The menu defaults are used only as a reference point; we set our own initial cooking time of 200℃ for 35 minutes and confirm completion by checking whether a bamboo skewer goes through easily.
