Remarks
Drying Roses - Use only pedals without pesticide.

Choose roses halfway open to get the sweetest pedals.  Gently grab entire bud to pull off pedals.

Discard any imperfect pedals.   No need to wash since no pesticide is used.

 Lay out the pedals in the dehydrator - make sure they do not overlap.

Set the dehydrator to 95 degrees for 6 hours.  Check every 2 hours for appropriate dryness.

For whole buds, choose buds that have not yet open.  Buds take about 12 hours to dry.

Dry red roses make a beautiful tea color, not to mention the phytochemical benefits.  The color of the roses leaches out quickly in hot water.  When roses are added to ice tea, it's a beautiful decoration.  When added to salad, it has a mild sweet flavor.  Almost all rose pedals are eatable.  Roses featured in above photos are Rosa Radrazz (Knock Out Roses).
