As someone who spent time as a Cub Scout, Boy Scout, and Explorer I enjoyed many camping trips. One device that amazed me was a "pie iron" or "sandwich iron". Some very enjoyable edibles were produced with this simple device. Here is one example, Amazon.com: Rome's #1705 Square Pie Iron with Steel and Wood Handles: Kitchen & Dining priced at $14.34. Today you can find many variations. The following recipe instantly brought to mind what a wonderful quick and easy Apple Pie for one or two that could be produced in a very primitive environment with this Jam and a couple slices of bread, and a pie iron. Amazing Apple Pie Jam ingredients; 1 lemon 6 cups mixed red and green apples (about 7 medium sized 1 cup water 1 tablespoon butter 3 cups sugar 2 cups packed light brown sugar 1 teaspoon ground cinnamon 1/4 teaspoon ground nutmeg directions; Zest lemon into a small bowl. Set both zest and lemon aside for later use. Add water, butter, and juice from 1/2 of the lemon (about 1 1/2 tablespoons) to a stockpot or large saucepan. Wash the apples, but do not peel. Remove the cores by quartering each apple lengthwise and cutting into each quarter on an angle. Using a food processor, finely chop the apples, with the skins on, until you have 6 cups in total. Add each chopped cup of apples directly to the lemon-water to prevent the fruit from browning. Add lemon zest and cook apples over medium-low heat until apples are soft, about 10 minutes. Stir frequently. When apples have softened, bring mixture to a rolling boil, and add in sugars, cinnamon, and nutmeg. Return mixture to a rolling boil and stir constantly for 7-10 minutes, or until mixture begins to thicken up. Ladle hot jam directly into hot sterilized jars, leaving 1/4" headspace. Place lids on jars and screw caps into place. Process jam jars for 10 minutes in a boiling water bath. Remove from water bath and set jars down in a cool, draft-free place to cool completely before moving to the refrigerator. (Jam will continue to set overnight in the fridge.) . Yield: 3 , pint-sized (16 oz) mason jars - the third jar will fall a wee bit short with the amounts listed above.
