Strawberry Jam
The gold standard. Bright, ruby-red, and sweet with just enough tartness.
Time: 45 minutes · Yield: 5-6 half-pint (250 ml) jars
Ingredients
- ●1.4 kg (5 cups) fresh strawberries, hulled and crushed
- ●60 ml (¼ cup) fresh lemon juice
- ●1 package (49 g) powdered pectin
- ●900 g (4½ cups) sugar
Method
- Prepare your water bath: fill a large pot with water and bring to a boil. Sterilize jars and keep them hot.
- In a large heavy-bottomed pot, combine the crushed strawberries, lemon juice, and pectin. Bring to a full rolling boil over high heat, stirring constantly.
- Add the sugar all at once. Return to a full rolling boil (a boil that doesn't stop when stirred) and boil exactly 1 minute, stirring constantly.
- Remove from heat. Skim off any foam with a spoon.
- Ladle hot jam into hot sterilized jars using a wide-mouth funnel, leaving ½ inch headspace. Remove air bubbles. Wipe jar rims clean with a damp cloth. Place lids and tighten rings to fingertip tightness (snug, not cranked down).
- Process in the boiling water bath for 10 minutes (start timing when water returns to a full boil after jars are submerged).
- Remove jars and let cool undisturbed for 12-24 hours. You should hear the lids "pop" as they seal. Check seals before storing.
- *Storage:** Sealed jars keep in a cool, dark place for up to 1 year. Refrigerate after opening and use within 3 weeks.
