Ingredients
Ingredients (Metric + Imperial)
Fruit / juice
Strawberries (whole, to prep): about 1.4–1.6 kg (about 10 cups whole strawberries)
Target yield: about 1.4 L (6 cups) strawberry juice/purée
Set + flavour
Lemon juice: 60 ml (¼ cup) (bottled is more consistent for pH)
Pectin (low/no-sugar type recommended):
1 package (box) or 8 Tbsp bulk pectin
Sweetener
Granulated sugar: 800 g (4 cups)
Plus 50 g (¼ cup) reserved to mix with pectin (taken from the 4 cups above)
Preparation
Juice / Strain Options (pick one)
Option A (easiest): Juicer
Juice strawberries until you have about 6 cups (1.4 L) juice.
Option B (blender/processor “seed-reduced”)
Blend strawberries 10 seconds on low (don’t fully liquify).
Let stand so seeds settle.
Skim any floating debris; carefully decant the liquid.
Option C (clearest jelly): Heat + strain
Crush berries by hand, warm gently until they break down.
Strain through jelly bag or cheesecloth for clearer juice.
Measure 6 cups (1.4 L) juice for the recipe.
1. Prep jars and canner
Wash jars and keep hot. Warm lids in hot (not boiling) water. Heat canner water so it’s ready for processing.
2. Prepare strawberry juice
Use one of the methods above to get 6 cups (1.4 L) strawberry juice/purée.
3. Measure sugar + prep pectin
Measure 4 cups (800 g) sugar. Remove ¼ cup (50 g) and mix that dry with the pectin (helps prevent clumps).
4. Boil juice + pectin + lemon
In a large pot combine:
6 cups strawberry juice
¼ cup (60 ml) lemon juice
Pectin mixed with the ¼ cup sugar
Bring to a full rolling boil (can’t be stirred down), stirring often.
5. Add remaining sugar + boil 1 minute
Add the remaining sugar (3¾ cups / 750 g). Return to a full rolling boil and boil hard for 1 minute.
Remove from heat.
6. Skim foam (optional)
Skim off foam for a clearer finished jelly.
7. Test set (optional but useful)
Cold spoon test (spoon in ice water). If too loose, add ¼–½ pack more pectin, boil 1 minute, retest.
8. Fill jars
Fill hot jars leaving 6 mm (¼ inch) headspace. Wipe rims, apply lids and bands fingertip-tight.
9. Process (water bath)
Process jars in boiling water with at least 5 cm / 2 inches of water above lids.
250 ml jars: 10 minutes at sea level to 1,000 ft
Adjust for altitude per standard water-bath guidance.
10. Cool and store
Cool 12–24 hours undisturbed. Check seals, label, store.
