Wash the tomatoes (no soap needed just a good rinse and possible scrub)
Cut the tomatoes into 1/4 inch slices and dispose of ends
Place onto food dryer trays tightly packed
Place the lid on top once filling your trays or when out of tomatoes
Turn on and let dry for at least over night or longer until fully dried
Let the tomatoes cool then use a thin metal spatula to pop off the slices
Store dried sliced tomatoes in an air tight container until ready to turn them to powder
Use a food processor or blinder (I have a Ninja that we use) to chop into powder form
Pour dried tomato powder into an air tight container with label and date for winter storage
