Cucumber Radish Sour Cream Cups
4 small spoon-served cucumber-radish cups, about 125–130 ml each · Active 30 min · Total 5 hr 30 min
Print recipe · PDFFinely cut cucumber and pink-edged radish give a cool sour-cream gel a little crunch. These are spoon-served cups, so they use a gentler set than an upright ring. Keep them in their glasses rather than trying to unmold a deliberately softer preparation.
A cup does not need to stand alone
Serving in a glass changes the goal. The gel should hold small vegetable pieces in a soft spoonful, without needing enough strength to support a tall freestanding shape. Four 180-milliliter glasses leave room for a spoon and a lid. There is no oiling or warm-water unmolding stage. Choose plain glass or food-safe cups without a narrow waist that makes the last bites difficult to reach.
Take the water out of the cucumber first
Peel, remove wet seeds and dice the cucumber finely. A brief salted refrigerator drain removes free liquid that would otherwise collect around the vegetables overnight. Weigh 80 grams after pressing rather than including the bowl of drained juice. Radish is washed and blotted, then cut into short fine matchsticks so its skin makes tiny pink lines rather than large hard crescents.
Dairy stays cool after dissolving
Gelatin dissolves in warm milk and water, then is tempered with a little sour cream before joining the cold remainder. Do not boil sour cream to force the gel to set sooner. Stir gently as the base begins to thicken in the refrigerator, add the dried vegetables and divide among glasses. Four hours is the minimum final chill for these small cups; a still-liquid center needs longer. Serve cold as a side with the rest of the meal selected separately.
Ingredients
- ½ cup finely diced peeled deseeded cucumber AFTER draining (80 g); prepare extra cucumber before its drain
- ¼ teaspoon fine salt (1.5 g), divided
- 1 standard ¼-ounce envelope unflavored powdered gelatin (7 g), of the specified setting strength
- 3 tablespoons cold drinking water (45 ml)
- ½ cup pasteurized whole milk (120 ml)
- ¾ cup plain pasteurized sour cream (180 g), kept cold
- ¾ cup very finely cut radish matchsticks (80 g), washed and blotted dry
- 1 teaspoon lemon juice (5 ml)
- 1 tablespoon finely chopped dill (2 g), washed and dried
- ⅛ teaspoon black pepper
Set out
Small sieve over a bowl, Knife and board, Clean cloth or paper towels, Scale, Small saucepan, Mixing bowl and whisk, 4 small glasses or food-safe cups of at least 180 ml capacity with covers, Refrigerator
Allergens
Milk. Check labels and substitutions.
Make it
- Toss prepared cucumber with half the salt in the sieve and drain in the refrigerator 15 minutes. Press gently in a clean cloth, then weigh 80 g. Keep cold. Prepare washed dried radish and clean covered serving cups.
- Bloom gelatin in 45 ml cold water in the small saucepan for 5–10 minutes. Add milk, warm over low heat while stirring just until completely dissolved, then take off heat before boiling.
- Whisk 3 tablespoons cold sour cream into the warm gelatin mixture gradually. Once smooth and lukewarm, whisk this into the remaining sour cream with lemon, dill, pepper and remaining salt. Refrigerate 15–25 minutes until beginning to thicken, stirring once or twice.
- Fold in dry cucumber and radish. Divide among four glasses, about 125–130 ml each, leaving below their rims. Cover and refrigerate at 40°F (4°C) or below for at least 4 hours until softly set throughout. The 5½-hour estimate includes draining and handling.
- Serve cold directly in the cups with a spoon; do not dip them in warm water or attempt to unmold. Return unserved cups promptly to refrigeration.
Gelatin starting strength
Use food-grade unflavored powdered gelatin with a manufacturer benchmark of 7 g for about 2 cups (500 ml) plain liquid. Weigh the stated grams: envelope sizes and powder density vary. A flavored dessert packet, collagen peptides, sheet gelatin or agar is not an equal substitute.
Cold service
This is an original retro-inspired recipe, not a recovered 1960s formula. Gelatin is animal-derived; the vegetable ingredients do not make the dish vegetarian. A reliable refrigerator and the stated earlier ingredient deadlines are essential.
Ingredient labels
Read milk, sour cream and gelatin labels and check relevant shared equipment.
A useful detail
The base contains 45 ml bloom water +120 ml milk +180 g sour cream +5 ml lemon, with 160 g drained/dried vegetables. Seven grams gelatin gives a soft cup set. A larger mold, drinkable dairy or wet cucumber is a different formulation and is not covered by this time or strength.
Another way
- Use 2 g finely chopped chives instead of dill for a different herb note.
- Use 180 g thick plain pasteurized Greek-style yogurt instead of sour cream, accepting a tangier soft spoon dessert-style texture while keeping it a savory side.
Keep it well
Keep covered at 40°F (4°C) or below. Use within 2 days of assembly or the earliest ingredient deadline, whichever comes first. Include the overnight setting period in that limit. Keep total unrefrigerated preparation and serving below 2 hours, or 1 hour above 90°F (32°C). Chill slices promptly after service; discard food exceeding those limits. Do not freeze; freezing damages the gel and releases water.
