Fellenberg, I believe, is considered similar to Italian, but as I said, I never have grown it. It tends to be rated a moderate cropper. I consider Italian here less than a moderate bearer so I'm guessing Fellenberg would likely be same. There's a lot of tricks I use to accelerate bearing so I'm not sure if Fellenberg actually can't be speeded up significantly. I consider Castleton a very flavorful prune plum but what makes it stand out is its reliability- it tends to set fruit in clusters almost like grapes. Some years other plums set little or no fruit but Castleton always seems to have a crop at all sites. It is also a natural semi-dwarf with a wonderful spreading branch habit. My favorite prune plum is Valor because it is very big and has that rich super-sweet quality and it can ripen from the last week of August here until the first hard frost. That is an extremely long picking time even for a prune plum. The reason I recommend Castleton over Valor is because of its consistency at many sites I manage. The funny thing is that at some sites plums are generally much more reliable than other sites for reasons I've never been able to decipher. That means that to really know what is best at your site you'd have to try several varieties and find out yourself but if you're just going to try one I think Castleton is your best bet. ACN carries it but you'd better order ASAP because the commercial growers are sucking it up.

Thank you for the advice and reassurance :) I tried it last night ... turned out pretty well, if I do say so myself! It is one of my first jams so I was fairly happy that it worked. I made 8 cups of fruit, and only used 1 package of pectin (which is only half what they recommend) but I figured that plums are a high-pectin fruit apparently and can be used without any pectin ... so I only put enough for the cherries. It "set" really well so I guess that was ok. I used basically the recipe I posted above except only 2 cups of sugar. It is certainly sweet enough like that but I was just worried because the sugar is meant to be the preservative, and I wanted there to be enough to be safe to store. If I used 2 cups of sugar with no-sugar-needed pectin and 8 cups of fruit, how long will it last on a shelf? Regular Jams usually seems to last a couple years, would this reduced-sugar option be less? I used allspice which was really nice with the plums and cherries. Tastes more like a fall jam than a summer one but that's ok ... it will keep till then. Next time I will try vanilla, that sounds incredible too!! Liqueurs are a great idea too, I hadn't even though of that aside from the Red Wine that was in one recipe I found. Thanks! I only had ground allspice but I understand what you mean about the cloudy jam ... mine doesn't seem to be (yet) but I will definitely keep that in mind and look for whole spices that can be removed :) So if I was going to use Sugar instead of Fruit Juice, would I just substitute it 1:1 Cup? The cherries seemed to be juicy enough without much added liquid so I don't think I'd need the juice for liquid. Next up (tonight hopefully) is Raspberry - Lemon Jam. Again, high pectin fruits so will try using 8 cups of fruit and only 1 pkg of no-sugar-needed pectin with 2 cups of sugar. Raspberries are pretty juicy too, I think.

Ken's right. Some European cookie presses (don't know about Mirro) include a fat long tube attachment for inserting cream and jellied fillings. OK, I promised some plum recipes. I used Italian Prune-Plums for these recipes. We have gobs of them available locally and they're meaty and sweet. I would guess these recipes would be more tart with some other varieties. I have loads of old recipes using plums, so if these don't fit the bill, let me know. The first is the only one I haven't made, so I can't personally vouch for it, but the combination sounds intriguing. Plum and Peach Conserve (from the Farm Journal Canning and Freezing Cookbook) 3 cups ground sweet plums (Italian prunes) 3 cups mashed peaches 6 cups sugar 2 medium oranges Combine plums, peaches and sugar in large saucepan. Add grated peel from 1 orange, juice from 2 oranges. Cook, stirring frequently, about 25 minutes or to desired consistency. Ladle into sterilized hot jars to within 1/8" of top. Wipe rims; adjust lids. Process BWB 5 minutes. Makes 4 pints. Plum Conserve (an old Kerr recipe) My oldest Kerr book provides the first version; a newer Kerr book the second minor variation: Plum Conserve (very, very rich) 4 pounds plums (8 cups cut up) 2 lemons (juice and grated rind) 6 cups sugar 1 pound seedless raisins 6 cups sugar 1 cup walnuts Wash plums, remove seeds, weigh fruit. Combine all ingredients except nut meats. Cook until thick. Blanch nut meats 2 minutes, drain, cut or chop. Add to mixture just before removing from heat. Pour into sterilized KERR jars and seal while hot. (BWB 10 minutes.) Plum Conserve #2 4 pounds plums (8 cups cut up) 4 tablespoons lemon juice 1 1/2 teaspoons grated lemon rind 1 cup seedless raisins 6 cups sugar 1 cup walnuts Same directions. Plum Conserve #3 (from So Easy to Preserve) 2 1/2 quarts chopped, pitted plums 3/4 cup thinly sliced orange peel 2 cups seedless raisins 1 1/2 cups chopped orange pulp (about 2 large) 6 cups sugar 2 cups broken pecan or other nuts Sterilize canning jars. Combine plums, orange pulp and peel, raisins and sugar; slowly bring to boiling, stirring occasionally until sugar dissolves. Cook rapidly almost to jellying point, about 15 to 20 minutes. As mixture thickens, stir frequently to prevent sticking. Add nuts the last 5 minutes of cooking. Pour hot conserve into hot jars, leaving 1/4-inch headspace. Wipe rims; adjust lids. Process 5 minutes BWB. This prune cake was posted by Lisbet at the Recipe Exchange; AnnT made the recipe but toasted the walnuts.

Source: "from the back of Sunsweet Prune box" I've had this recipe about forever. Don't remember the source. My notes say it's a "simple homely dessert or snack - almost a coffee cake." 1 1/2 cups chopped purple plums 1 cup sugar 1/2 cup brown sugar 3/4 cup vegetable oil 1 egg, beaten 1 tsp. grated orange peel 2 cups flour 1/4 tsp. salt 1 tsp. baking soda 1 cup buttermilk Nut Topping: 1/4 cup sugar 1/4 cup chopped nuts 1 tsp. cinnamon Pit and chop plums to measure 1 1/2 cups. Set aside. Blend sugars, egg and orange peel. Sift dry ingredients. Add to sugar mixture alternately with buttermilk, stirring well after each addition. Stir in plums. Pour into greased 9x13 pan. Sprinkle with topping. Bake 350 35 minutes. Serve warm with whipped cream. Now that I've remembered this one, I'm making it tonight. And finally, this recipe, including my notes from the first time I baked it. Purple Plum Pie Recipe By : Farm Journal's Best-Ever Pies Categories : Desserts  Pies and Pastries Amount Measure Ingredient -- Preparation Method -------- ------------ -------------------------------- 4 cups sliced, pitted purple plums (1 1/2 pounds) 1/2 cup sugar 2 tablespoons cornstarch 1/4 teaspoon cinnamon 1/4 teaspoon salt 1 unbaked pie shell (9-inch) 1 tablespoon lemon juice Spicy Topping 1/2 cup flour 1/2 cup sugar 1/4 teaspoon cinnamon 1/4 teaspoon nutmeg 1/4 cup butter or margarine Combine plums, sugar, cornstarch, cinnamon and salt in bowl; mix well. Arrange plum mixture in unbaked pie shell. Sprinkle with lemon juice. Prepare Spicy Topping and sprinkle over plum mixture. Place pie in brown paper bag. Fold over open end twice to close and fasten with paper clips. Carefully place on baking sheet. Bake in 425° oven 45 minutes or until plums are tender. Cool on rack. Makes 6 to 8 servings. NOTES : I didn't bake this in a paper bag. (Images of my oven on fire!) I baked at 400 15 minutes and then 350 approximately 45 minutes (hour total). This is an incredible recipe, perfect proportion of spices. The only complaint is 2 tablespoons of cornstarch was insufficient for the juicy plums. I would use more thickening, probably a mixture of flour and tapioca. This pie is very "drippy." Next time I'll use a baking sheet. Carol

It isn't always the case that it's simply undissolved or recrystallized sugar. If you taste one of the grains.. If it's really sweet, it's sugar. If it isn't and can even be very bitter, it's undissolved pectin that has gelled to itself like a grain of chia. There are instanced of pectin that require calcium not dissolving in the presence of too much sugar, too quickly in the recipe. Lower sugar pectins suffer from this problem. I discovered and looked into it a lot when a regular sugar jelly we make had a grainy and liquidy, despite being the exact same recipe. Reboiling (in this instance) at a very high heat for a few minutes helped a lot, but didn't really fix it entirely. The solution is to dissolve the pectin into any other low sugar liquids along with the fruit, before adding the sugar. Just another one of many things it can be I guess. :)
