1poundfresh gooseberries(any variety; we're using purple gooseberries in the photos), cleaned and tops and tails removed
1 1/2cupsgranulated sugar(can use a little more sugar if the berries are underripe or especially tart)
Place the gooseberries in a large pot with the water and lemon juice. Bring it to a boil, reduce to medium-high heat, and simmer for 10-15 minutes, stirring occasionally, until the gooseberries are softened. Stir in the sugar, return to a boil, and stir until dissolved. Mash the gooseberries to further break them up. Continue to boil for 25-35 minutes, stirring frequently, until the mixture reaches gel stage. This can be determined by using a thermometer (when it reaches 220 F the jam is done) or performing a gel test (see below).To perform a gel test: Place a plate in the freezer (put it in the freezer ahead of time while the jam is boiling). Remove it from the freezer, drop a spoonful of hot jam onto it, and return it to the freezer for 2 minutes. Remove the plate and use your finger to nudge the jam. If the jam wrinkles it is done. If it doesn't, return the plate to the freezer, continue boiling the jam, and test it again every few minutes.
Ladle the hot jam into hot sterilized jars leaving 1/4 inch space from the top. Wipe the rims clean with a damp cloth. Close the jar and let cool completely before placing the jars in the fridge where the jam will keep for at least a month. Canning for long-term storage: Ladle the hot jam into hot sterilized jars leaving 1/4 inch space from the top. Wipe the rims clean with a damp cloth. Place the lids on the jars and screw shut. Process the jars in a water canner for 5 minutes. Carefully remove the jars and let them sit undisturbed for 24 hours. Transfer to a cool, dark place where the jam will keep for up to a year.
