I always look forward to making jam using "organic seasonal fruits" from my neighbors.I did not boil the kumquats before making the jam. My kids really like it.Please adjust the amount of sugar depending on the sweetness of the kumquats. Recipe by Shingu shokudou

I unexpectedly received Kumquats as a gift! Similar to Yuzu Jam, I experimented several times and came up with this good recipe.This is a less soured recipe. If you like more sour taste, reduce the amount of sugar and adjust the amount of lemon juice. Recipe by Kattasan

Every fall, my mother never fails to make this jam, so this time, I asked for the recipe.If you increase the amount of sugar by 30-40%, it will have a long shelf life.This recipe uses a reduced amount of sugar, so the jam should be consumed quickly. Recipe by suzu-ren

I wanted to make a jam because some persimmons I had received became too soft.If you use persimmons that aren't overripe, slice them thinly and let them sit for an hour after mixing with the sugar to make syrup. You do not need to add the 50 ml of water if you do it this way (you can add the water if not enough syrup formed). I used 25% as much sugar as the persimmons. Please adjust this amount to your taste. Recipe by ankobby

I received a bunch of persimmons from a friend, and when thinking of various ways to use them, I decided to make persimmon jam, since I've never had it before.After searching different recipes on the internet, I came up with my own version.Persimmons are more tart than apples, so it only need a little sugar.You can use either firm or ripened persimmons, so give this recipe a try when you have lots.You could also grate or put them in a food processor for a smoother texture.

If’n y’all like persimmons, you’ll love this jam. I’d wanted to make jelly, it’s too pulpy to be clear. So, jam it is! Either way, my Daddy said it was “good on a biscuit”! #GoldenApron23

I grew some butternut squashes in my garden.All you have to do is boil the squash, mash it, and cook it down.Since this jam doesn't contain dairy products, unlike kabocha cream, it keeps for a long time.If you use butternut squash, this jam will be nice and creamy. If you decide to use kabocha squash instead, choose ones that are fluffy. Recipe by cafe-cafe

We received a lot of freshly picked lemons as a gift.The cooking time will vary depending on how strong the heat is, so adjust.By not simmering it for too long, you can preserve the fragrance and color of the lemons.If you leave the white pith, it will be bitter. Thinly peel off just the zest using a vegetable peeler.You don't have to parboil the zest - it will still be delicious. Recipe by Yukijirushi

I was given a lot of mandarin oranges and wanted to use them up.Adding starch based sweet syrup makes the jam lustrous and beautiful, but you don't have to use it. Please adjust the amount of sugar depending on the sweetness of mandarin orange. Turn off the heat while the mixture is still runny. When it's cooled, it thickens. Recipe by shoken mama

Watson pomelo jam, lemon jam. I've made all sorts of jam with citrus fruits. So, I decided to make jam with tangerines as well.You could also use regular sugar if you don't have granulated sugar.The amount of granulated sugar should equal 60% of the weight of peeled tangerines.Make sure not to reduce too much when simmering. It will become extremely thick. Recipe by FarmersK

We received clementines as a gift, but they were rather sour. I turned some of them into jam before they went bad.The final simmering over medium heat is to evaporate the moisture. Stop cooking when it is nicely thickened. Be careful not to let it burn.This recipe is good for rather sour oranges. For sweet oranges, use less than 100 g of sugar.If you don't use granulated sugar, it may end up too sweet. Recipe by Rugyaraga-

There are many ways to make ume plum jam, such as adding the sugar at the start and simmering the whole plums but if you do that, you may throw out some of the sugar with the stones, and it also makes it harder to pass the jam through a sieve. If you use this method, I think you only need to cook the jam for the minimum amount of time, and you'll also only add the minimal amount of sugar. I simmered the jam 500 g at a time in an enameled pan. This cuts down on the overall cooking time, and I had jam in two colors, which made me happy.Change the water 3 to 4 times for hard green plums, and 2 to 3 times for ripe plums, and they will become tender. Don't bring the water to a boil to prevent the plum skins from ripping. Add 70 to 80% of the weight of the plums in sugar. I think it's best to add more than 350g of sugar for every 500g of green plums. This jam becomes quite stiff when cold. When it changes color after 15 minutes of simmering and becomes thick and limpid, try dropping some of the jam in cold water. If it stiffens up it's done. Recipe by commeline
