Cook's tips
- There are a few golden rules for making jams, jellies and marmalades. Use dry, unblemished and not overripe fruit. Jam sugar is specified for one of these recipes – this is sugar with added citric acid and aids the setting of jam when using fruit with little natural setting agent (pectin), such as strawberries.
- All equipment must be scrupulously clean. First of all your jars and lids must be sterilised. If you have a dishwasher, put them through a high heat cycle (or wash and rinse them well in hot water) then place them on a baking tray and slide into a hot oven (gas mark 3/160˚C/fan 140˚C/325˚F) for 10-15 mins. Keep them warm until you pour in the jam. Always seal jams etc while hot.
- Use as little water as possible and cover the fruit with a tightly fitting lid. Skim the scum frequently while the jam is boiling or add a small knob of butter to disperse it.
- To test for a good set put a few saucers into the freezer before you start to cook the jam. When it has been boiling rapidly for 15-20 mins or so, take a saucer from the freezer and drop a small spoonful of jam on to it.
- Allow it to cool for a minute then push your finger through the jam – if it wrinkles it’s ready; if not, boil for a few more minutes. Continue testing until a set has been reached.
Always remove the jam from the heat while you’re testing so that if it’s ready you won’t overcook it. |
