Because you are provided the luxury of grilling indoors with an electric grill, you want to reduce the amount of smoke that is emitted. If some smoke is inevitable, then you should still be using the grill in properly ventilated areas. But, one way you can reduce smoke is to prevent the drip tray from becoming too hot. When drippings fall onto a hot drip tray, it can cause smoke but this can be avoided.
What you need to do is add around 16 ounces of water (or another liquid) into the tray. Besides allowing the drippings to fall into the water and eliminate the smoke, this can also infuse your meats with more moisture as the tray will be in close proximity. So, get creative on the liquid you use as this can be an ideal way to enhance the flavor of your meats.
