Preheat oven to 120 degrees (or lowest temperature available for your oven)

In a steamer pot, boil water and place strawberries and cranberries in steamer basket and steam for 10 minutes until soft.

Combine steamed fruit with lemon and 1/4 cup of water from pot in a blender or food processor and blend. Puree to a smooth texture. (If using for baby food, take out the portion you will need before adding in honey.) Add honey and blend again.

Prepare a sheet pan with a piece of heat resistant plastic wrap or sprayed parchment paper and pour the puree on the sheet in a very thin layer, about 1/4 inch thick.

Bake, with oven door left slightly ajar, for about 3 hours, until fruit puree has dried.

Cut with a pizza cutter into long strips, the full length of the pan, and then cut those in half, and finish up by rolling them. Store in a air-tight glass jar.
