Plum Jam without Pits
Instructions
I prepare necessary components for pitted plum jam.
In boiling water: immerse plums in SMALL BATCHES (not all at once). Hold ~5 MINUTES.
Fish out fruits that begin to FLOAT with slotted spoon; place in separate container. Skin starts to crack + peel off by this time.
When plums cool enough to handle without pain: SQUEEZE OUT pits + remove skins. Process goes very easily + quickly. Shape suffers but doesn't affect final result. Excess juice (released from pulp): pour off to adjust thickness.
Pour processed fruits with SUGAR.
Mix ingredients.
Place over moderate heat; simmer 5 MINUTES from start of boiling. Foam accumulates — REMOVE.
Turn off heat; let jam infuse in sweet syrup for 8 HOURS. Sterilize glass containers + metal lids meanwhile. 9. BOIL plums again — this time for 25 MINUTES. Be sure to remove forming foam.
Pour BOILING jam into jars.
After sealing: turn jars UPSIDE DOWN — lids receive additional thermal treatment. After 20 minutes: return to original position; NO TOWEL WRAP needed. Amber-sunny plum jam without pits has distinctive smell + unmistakable taste. Even simple bun transforms with this jam; liquid syrup-part diluted with water = glossy crust on pies. Bon appétit!
Tips

THE BLANCH-AND-PEEL TECHNIQUE. Steps 2-4's "boil 5 min + cool + peel + pit" is signature pit-removal method. Direct knife pit-removal: requires firm fruit + lots of work + plums are often too small. BLANCH method: heat causes skin to crack naturally + flesh to soften, pit pops out under thumb pressure, skin peels off in one piece. The 5-min blanch is calibrated — shorter doesn't loosen pits, longer cooks plums into mush. Same hot-water blanch principle: French fruit-peeling traditions, Italian pelati preparations. Don't shortcut to direct cutting — blanch saves time + reduces hand fatigue significantly.

THE 1:1 SUGAR RATIO BY PITTED-WEIGHT. Recipe's "500 g sugar = 1:1 with pitted plums" is precision-recipe principle. Measuring sugar by RAW plum weight (with pits): too much sugar (pits add ~17% weight = useless mass), result too sweet + cloying. Measuring by PITTED weight (recipe-canonical): perfect sweet-tart balance, plums bright + flavorful. The 1:1 ratio (vs lower-sugar alternatives): provides preservation + traditional Russian "varenye" sweet character. Same precision-ratio principle: French confitures, English jams, traditional Slavic preserves. Use kitchen scale for accuracy — eyeballing sugar produces inconsistent results.

THE 8-HOUR INFUSE + 25-MIN FINAL BOIL. Steps 8-9's two-stage technique is recipe-defining. SINGLE-stage long boil (1 hour straight): plums turn to mush, marmalade-without-pieces result. TWO-STAGE method: 5-min initial boil + 8-hour rest in syrup (sugar penetrates plum cells, plums hold shape) + 25-min final boil (concentrates syrup, develops final character). Result: plums hold shape + amber translucent character + signature MARMALADE-LIKE consistency from controlled cellulose breakdown. Same gradual-method principle: traditional Russian "varenye", French confitures-aux-fruits-entiers. Don't shortcut — full 8-hour rest essential for proper structure.

THE NO-WRAP UPSIDE-DOWN COOLING. Step 11's "no towel wrap needed" is genuine recipe-specific note. Standard canning: requires towel-wrap thermal bath for 8+ hours. THIS PITTED-JAM recipe: pectin-rich plum content + 25-min final boil + immediate hot-pour into sterilized jars provides sufficient sterilization without extended thermal bath. The brief 20-min upside-down: ensures lid contact + minimal vacuum formation = perfect seal. Why simpler? Higher sugar concentration (1:1) acts as preservation, eliminates need for extended sterilization. For another classic Russian fruit preserve worth trying, try Strawberry Five-Minute Jam.
FAQ
What's "alycha" plum? +
Russian/Caucasian name for cherry plum (Prunus cerasifera) — small yellow + red fruits, more sour than European/Japanese plums. CHARACTERISTICS: ~2-3 cm diameter, thin skin, very juicy + tart flesh, soft pit. ORIGIN: native to Caucasus + Central Asia + Middle East. Traditional Slavic preserves treasure alycha for: high pectin content (excellent jam-setting), bright color, distinctive tart-sweet character. SUBSTITUTES: regular yellow plums, mirabelle, greengage, even sour cherries (different but functional). Recipe-canonical alycha: more accessible at Russian + Eastern European groceries; can substitute with sour-tart plum varieties at Western groceries.
How is this different from with-pit version? +
Three key differences. STORAGE TIME: pitted version stores INDEFINITELY (no amygdalin from pits leaching into jam over time). With-pit version: 1-year limit recommended. PREPARATION TIME: pitted version 9 hours total (including 8-hour rest), with-pit version 6+ hours but more active steps. TEXTURE: pitted version achieves more uniform marmalade-like consistency, with-pit version has whole-fruit format with pits inside. APPEARANCE: pitted = honey-amber liquid with fruit pieces, with-pit = whole fruits in syrup. Both versions are recipe-canonical Russian "varenye" — choose based on storage needs + preferred presentation.
How long does it really keep? +
Properly sealed jars: UP TO 2 YEARS at room temperature (no pit-bitterness concerns). Year 1: peak fresh-fruit character. Year 2: still excellent, slight color darkening + flavor concentration. Past 2 years: still safe but quality diminishes (sugar crystallization possible). COOL CELLAR (10-15°C): extends quality to 3 years. Once OPENED: refrigerate, consume within 1 month. Storage tips: clean dry spoon between uses, tight lid, dark place. Spoilage signs: surface mold, fizzy bubbles, off-smell — discard. The pitted format is genuinely longer-storage option than with-pit version.
How do I serve it? +
Russian/Slavic tradition has classic alycha-jam companions. CLASSIC: spoon into bowl alongside hot tea (most iconic Russian "tea drinking" tradition). BAKING: spread on bun/toast at breakfast, spoon onto pancakes (bliny + alycha = peak Russian comfort food), filling for piroshki + russian-style strudels. DESSERT: layered into Napoleon cake, drizzled over vanilla ice cream, spread on shortbread cookies. PIE-TOP GLAZE: dilute liquid part with water, brush on baked pies for glossy crust (recipe-suggested). MEAT PAIRING: surprising but excellent — accompanies pork roast, duck breast, lamb (sweet-tart contrast). Russian families: open jar + serve in bowl alongside everything.
