Our serving size is 1/2 ounce (about 1 cup when puffed). Empty package onto a microwave approved plate. Spread the pellets so they won't stack up on top of each other. Consider your first batch to be a test batch. This is because microwave ovens cook at different rates. Start with a time of 2 minutes. (If you cook less than the whole package example ¼ cup will puff in 90 seconds in the microwave) If some of the pellets don't puff up all the way, or if a few burn, adjust the time up or down by ten or fifteen seconds. They don't make any noise as they puff up. Let sit for about 30 seconds after cooking to achieve that crunchy taste. If you pop up more than you can eat, keep them in a zip lock bag for later. The microwave pellets should not be refrigerated and may be stored for a year at room temperature.
