Reheating for the First TimeTimer DialNo temperature setting / 4min
After 2 minutes, place the basket on a trivet. Heating will stop, but the timer will continue to run. Flip all 4 pieces at once, swapping their front and back sides. Remove any pieces where the batter has started to burn, and reset the timer dial to 0. Remove any pieces where the batter is hot and dry all the way to the center of the shrimp to a clean plate. Return only those pieces that are cool in the center and not burnt to the plate, and continue heating for the remaining time on the dial. If you notice smoke, an unusual odor, or an error indicator, stop immediately, discontinue use, 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.
Reheat the shrimp tempura—which has been thoroughly cooked through after purchase or preparation—from a chilled state according to the product label. This is not the traditional tempura method of coating raw shrimp in batter and frying it.
Check Before Cooking
Attach the plate to the cooled unit with the convex side facing up. Do not preheat or set the temperature.
Use 4 pieces of pre-cooked shrimp tempura (a total of 120g) that have been heated all the way through after purchase or cooking, with a maximum batter-covered body thickness of 18mm or less. Store in the refrigerator according to the product label; use only items that are within their use-by date and free of sauce or moisture. Do not substitute with raw shrimp, uncooked tempura batter, frozen products, mixed platters, or kakiage.
Do not use additional oil. Do not line the plate with aluminum foil, parchment paper, or a heat-resistant container; place the food directly on the plate. Do not use items where the coating has come off or is wet.
Arrange the shrimp tempura in a single layer so they do not overlap or touch each other. Make sure the tails are not near the heating element and that the ventilation holes and the “MAX” line are not blocked. Do not start heating if all 4 pieces do not fit. Do not estimate cooking time based on the quantity and arrangement relative to the number of servings or the capacity.
Do not leave the area while cooking, and do not block the air intake or exhaust vents. Do not use the appliance if batter residue has fallen inside. If you notice smoke, a burning smell, or any other abnormalities, stop heating and discontinue use in accordance with the instruction manual.
If you remove the basket midway through, the heating will stop but the timer will continue to run, so check the remaining time on both an external clock and the timer dial. When setting the timer for 4 minutes, turn the dial past the 5 mark once, then turn it back to the 4-minute mark.
Instructions
01
Check the refrigeration status and quantity
Check the storage instructions and use-by date on the product label. Weigh 4 refrigerated, fully cooked shrimp tempura pieces and confirm that they total 120g and that each body is no more than 18mm thick including the coating. Do not use pieces with sauce, moisture, or substantially detached coating. Do not add oil.
Weigh 4 refrigerated, pre-cooked shrimp tempura sticks and check the weight and thickness listed in the ingredients section.Discuss these instructions
02
Prepare the plate
Place the plate onto the cooled basket with the convex side facing up. Do not preheat, and do not adjust the temperature setting.
Arrange them in a single layer without using a sheet
Without using aluminum foil, parchment paper, or heat-resistant containers, place 4 shrimp tempura sticks directly on the plate. Do not stack them; space them so they do not touch each other, and keep the tails away from the heating element. Make sure not to block the ventilation holes or the “MAX” line.

04
Set the initial time to 4 minutes
Turn the timer dial to a setting of 5 or higher, then turn it back to the 4-minute mark to start. After 2 minutes, place the basket on a trivet, flip the 4 pieces over, and switch their front and back positions. Since the timer continues to run even while the basket is removed, check the food midway through cooking according to the guidelines in the “Cooking Stages” section. Return only the pieces that need to be cooked further to the unit and cook for the remaining time shown on the dial.
Once the set time has elapsed, place all 4 shrimp—including any that were removed early—on a clean plate and crack them open. Serve only if each shrimp is hot all the way through to the center, has no cold spots, has a dry coating surface, and shows no signs of burning or hard spots. If even 1 shrimp is cold in the center, remove the entire batch and proceed to the final check. Do not assume the dish is ready based on surface color alone.

06
Serve without a lid
Transfer the shrimp tempura that meets the readiness criteria to a clean plate. Do not cover with a lid or plastic wrap to prevent the batter from becoming soggy, and eat while still warm. If using tempura dipping sauce, serve it in a separate bowl after reheating the shrimp tempura.
If the food does not meet the completion criteria, do not reheat or consume it. Check the product label or the official instructions for the same model number to confirm the proper method for the quantity, thickness, and initial state of this food. If you cannot confirm this, do not add time based on guesswork.
Break open all 4 shrimp tempura, including any removed midway, on a clean plate. Check that the center of each shrimp is hot with no cold part, and that the coating is dry with no burned or hard part. If even 1 shrimp has a cold center, do not eat it and proceed to the final check.
Can I use it on raw shrimp or tempura before frying?
This method cannot be used. It is intended only for 4 pieces of shrimp tempura that have been thoroughly cooked through and then refrigerated after purchase or preparation. Raw shrimp, uncooked batter, and frozen products require different cooking instructions.
Is it okay to line the bottom with aluminum foil or parchment paper?
Do not line the appliance for this recipe. Covering the bottom or air vents restricts hot-air circulation and causes uneven drying and heating of the coating. Do not use a heat-resistant container; place the shrimp tempura directly on the specified inner rack, plate, or rack in a single layer.
Will adding more oil make the batter crispier?
Do not add any additional oil. Reheat the food using the residual oil remaining in the batter from the initial frying; do not use a pool of oil or cooking spray. Do not use this method if the food is covered in sauce or water.
Can I heat up the vegetable tempura and kakiage at the same time?
Do not reheat them together. Since the thickness, moisture content, and amount of batter vary, we’ll limit this to 4 shrimp tempura for now. We will not adjust the quantity or time for mixed platters, kakiage, chikuwa tempura, etc.
Can I put it in right after taking it out of the fridge?
Refrigerate the product according to the package instructions, then check the quantity and the condition of the batter before adding it. Do not use products that have passed their expiration date, have been left at room temperature for a long time, or have been frozen.
How the Recipes Were Created and Sources Consulted
Standards verified in official documents
Example: Reheat 200g of pre-cooked fried chicken thighs (delicatessen) for 4〜6 minutes using the timer dial. The table does not specify the starting temperature, thickness, or placement.
Independently designed details and unverified points
The official example uses 200g of pre-made chicken karaage; it is not an example for shrimp tempura. This guide uses unique conditions: place 4 pre-cooked, refrigerated shrimp tempura sticks (totaling 120g, with a body thickness of 18mm or less, including batter) on the plate in a single layer, provided they are within their best-by date. Since the batter, food, quantity, starting temperature, thickness, and arrangement differ, do not use the official example’s cooking time as a guarantee of completion or a weight-proportional conversion. Instead, independently design the process using the minimum initial time of 4 minutes, check the progress at the 2-minute mark, and verify the center of all 4 pieces and the batter condition. Stop cooking if burning or abnormalities occur; do not eat if the target is not reached; and do not perform additional heating without a valid reason.
