Heating up cold tomatoes in a microwave without cooking them can be a delicate process, as microwave ovens tend to heat food quickly and can sometimes cause the tomatoes to become mushy or overcooked. Here's a method to gently warm up cold tomatoes in a microwave while minimizing the risk of cooking them:
Slice or chop the tomatoes: If the tomatoes are large, slice or chop them into smaller, evenly-sized pieces. This will help ensure more even heating.
Arrange on a microwave-safe plate: Place the tomato slices or pieces on a microwave-safe plate in a single layer. Avoid stacking the tomatoes, as this can lead to uneven heating.
Microwave on low power: Set your microwave to a low power level (around 30-50%) or use the "Defrost" setting if available. Lower power levels will help heat the tomatoes more gently, reducing the risk of cooking them.
Microwave in short intervals: Heat the tomatoes in short intervals, such as 10-20 seconds at a time. After each interval, check the tomatoes to see if they have reached the desired temperature. Stir or rearrange the tomatoes on the plate to promote even heating.
Use a microwave cover: Consider using a microwave-safe cover or a microwave-safe paper towel to cover the plate loosely. This can help trap steam and retain moisture, which will aid in gently heating the tomatoes.
Stop heating before they start to cook: Be attentive during the microwaving process, and stop heating as soon as the tomatoes are warmed to your liking. Remember that even at low power levels, microwaves can heat food quickly.
Let them rest: Once the tomatoes are warmed, remove them from the microwave and let them rest for a minute or two. This will allow the heat to distribute more evenly throughout the tomatoes.
By using a low power setting, short intervals, and a microwave cover, you can gently warm up cold tomatoes without fully cooking them. However, keep in mind that the results may not be the same as reheating them on a stovetop, as microwaving can still cause some textural changes in the tomatoes. If you're looking to maintain the tomatoes' raw texture entirely, consider letting them come to room temperature naturally instead of using the microwave.
