PUREE THE FRESH FRUIT WITH THE LEMON JUICE IN A BLENDER OR FOOD PROCESSOR UNTIL VERY SMOOTH AND PUREED.
IF YOU ARE USING APPLESAUCE, MIX TOGETHER THE APPLESAUCE AND LEMON JUICE IN A MIXING BOWL.
INVERT A COOKIE SHEET AND COVER THE FLAT BOTTOM WITH A HEAT RESISTANT PLASTIC WRAP. TAPE THE WRAP TO THE COOKIE SHEET WITH MASKING TAPE.( THIS PREVENTS THE EDGES FROM PULLING AWAY WHILE THE FRUIT IS DRYING).
POUR THE FRUIT PUREE ONTO THE PLASTIC WRAP AND SPREAD ABOUT 1/4" THICK.
PLACE THE COOKIE SHEET IN A PREHEATED 140° OVEN WITH THE OVEN DOOR OPEN AT LEAST 2". ALLOW THE PUREE TO DRY IN THE OVEN FOR ABOUT 3 HOURS, OR UNTIL LEATHERY, BUT STILL PLYABLE. CUT INTO STRIPS AND ROLL UP. STORE IN AN AIRTIGHT CONTAINER.
APPLESAUCE ROLL UP:
LINE A BAKING SHEET WITH PLASTIC WRAP. TINT 2 CUPS OF SMOOTH APPLESAUCE WITH RED FOOD COLORING. SPREAD IT THINLY ON THE WRAP. BAKE IN A PREHEATED 150° OVEN FOR 6 TO 8 HOURS. REMOVE WHEN APPLESAUCE LOOKS LIKE LEATHER. WHEN IT IS COOL, PEEL WRAP OFF AND ROLL UP.
YOU CAN USE A 3 OUNCE BOX OF JELLOW AND 4 CUPS OF APPLESAUCE. OR ANY FLAVOR YOU LIKE, JUST FOLLOW THE DIRECTIONS FOR DRYING AS DIRECTED ABOVE.
