Ok, here are some instructions on how to can loquats, which are very delicious canned (my kids prefer canned to fresh). They are often overlooked, but are in season right now. Please ask before taking from any tree that isn't yours. See below for photo of ripe loquats from my tree.
For the most economical storage, use narrow mouth quart jars. I usually use 4 oz narrow mouth jars for single serving fruit cups (great for school lunches back when kids were going to school). Narrow mouth pint jars are also good if you can't finish a quart jars before it spoils (they will keep about a week in refrigerator once opened).
After harvesting loquats (afternoon/early evening is best), you should rinse them. They can then be stored overnight in refrigerator or keep going.
The next step is to de-stem them, cut them in half, and remove seeds, blossom end, and peel. Once you have extracted the flesh, immediately immerse it in water to which you have added Vitamin C powder (the best choice, about 1 tablespoon per 6 quarts/liters of water). If you don't have Vitamin C, you can also use lemon or lime juice, or even vinegar, but they won't keep as long in refrigerator. You can refrigerate them in this acidulated water for several days. They will turn brown quickly if you skip this step. See below for what they should now look like.
Now it is time to can them in boiling water. Make sure to use Mason jars with brand new lids or similar jars designed for canning (don't reuse grocery store jars). The first step is making the canning syrup (which helps preserve them). For best flavor, use light syrup (1 cup sugar plus two cups water, boiled to combine). It is ok to use natural or turbino sugar, but it may be a bit darker than white sugar. If you are going to keep them for more than a year, use medium syrup (3 cups sugar, 4 cups water). See recipe below.
Once you bring the syrup to a boil, drain loquats from acidulated water and add to syrup, cooking for 2-4 minutes. Then use ladle and canning funnel to transfer to pre-sterilized jars. (Sterilize jars by boiling in plain water, with a splash of vinegar added if you have hard water). Wipe the rims, place sterilized lids & bands on, tighten and return to boiling water bath (any pot deep enough to cover top of jar). Boil for 15 minutes for pint or smaller jars, 20 minutes for quart jars. This step is very important as it kills the spoilage organisms in your fruit, so use a timer for precision. Once processed for necessary time, remove from the boiling water and cool for 24 hours. After at least 24 hours, remove bands (cleaning and saving for later). Then wash jars well to remove any residue from exterior. Label lid with date & contents so you know what it is. Store jars in cool, dark place (like a basement) until ready to use. Refrigerate after opening (if you have leftovers). See below for final product (canned with raw sugar powder).
